How long is a 2011 pistol? A full-size 2011 like the Staccato P is 8.1 inches long (20.57 cm) with a 4.4-inch barrel. Across the popular models, a 2011 measures 7.1 to 9.1 inches long (18.03 to 23.11 cm): the compact Staccato CS is 7.1 inches, the P is 8.1 inches, the XC is 8.7 inches, and the longest common model, the Staccato XL, is 9.1 inches. A 2011 weighs about 23 to 41 ounces (652 to 1,160 grams) unloaded, or about 1.44 to 2.56 pounds.
The 2011 is a double-stack, 1911-style pistol. It keeps the classic 1911’s single-action trigger, but its grip is wider because it holds a double-stack magazine — 17+1 rounds of 9mm instead of the classic 1911’s 7+1 rounds of .45 ACP.
2011 Pistol Length at a Glance
| Measurement | Inches | Centimeters | Millimeters |
|---|---|---|---|
| Overall length, Staccato CS (compact) | 7.1 in | 18.03 cm | 180.3 mm |
| Overall length, Staccato C2 | 7.5 in | 19.05 cm | 190.5 mm |
| Overall length, Staccato P | 8.1 in | 20.57 cm | 205.7 mm |
| Overall length, Kimber 2K11 | 8.56 in | 21.74 cm | 217.4 mm |
| Overall length, Staccato XC | 8.7 in | 22.10 cm | 221.0 mm |
| Overall length, Staccato XL (longest) | 9.1 in | 23.11 cm | 231.1 mm |
| Barrel length, Staccato P | 4.4 in | 11.18 cm | 111.8 mm |
| Height, full-size models | 5.9 in | 14.99 cm | 149.9 mm |
| Width, full-size models | 1.5 in | 3.81 cm | 38.1 mm |
| 9mm bullet diameter | 0.355 in | 0.90 cm | 9.02 mm |
Quick tip: a 2011’s overall length is mostly set by its barrel: each extra inch of barrel adds roughly an inch of overall length. Always check the manufacturer’s listed overall length for the exact model, because grips, magwells and compensators change the number by a few tenths of an inch.
How Long Is a 2011 Pistol with a 4.4-Inch Barrel?
A 2011 pistol with a 4.4-inch barrel is 8.1 inches long — 20.57 centimeters (205.7 mm), or 0.67 feet. The best-known example is the Staccato P, the full-size duty pistol that made the 2011 famous outside competition shooting. Per Staccato’s own specifications, the P measures 8.1 x 1.5 x 5.9 inches (length x width x height), weighs 33 ounces (935.5 grams) unloaded, and holds 17+1 rounds of 9mm, or 20+1 with an extended magazine. Its 4.4-inch barrel is 11.18 centimeters (111.8 mm) long.
2011 Pistol Barrel Lengths: 3.5, 3.9, 4.4, 5 and 5.4 Inches
The 2011 comes in five common barrel lengths. All figures below are from Staccato’s official specifications, except the Kimber 2K11, which is from Kimber’s published specifications as listed by multiple retailers.
- 3.5-inch barrel: the smallest 2011, the Staccato CS. It is 7.1 inches long overall (18.03 cm), 5.4 inches tall (13.72 cm), 1.45 inches wide (3.68 cm), and weighs 23 ounces (652 grams, 1.44 pounds). It holds 15+1 rounds of 9mm — the concealed-carry 2011.
- 3.9-inch barrel: the Staccato C2. It is 7.5 inches long overall (19.05 cm), 5.5 inches tall (13.97 cm), 1.49 inches wide (3.78 cm), and weighs 25 ounces (708.7 grams, 1.56 pounds). It holds 16+1 rounds of 9mm.
- 4.4-inch barrel: the Staccato P. It is 8.1 inches long overall (20.57 cm), 5.9 inches tall (14.99 cm), 1.5 inches wide (3.81 cm), and weighs 33 ounces (935.5 grams, 2.06 pounds). It holds 17+1 rounds of 9mm, or 20+1 with an extended magazine.
- 5-inch barrel: the Staccato XC and the Kimber 2K11. The XC is 8.7 inches long overall (22.10 cm) and weighs 37.56 ounces (1,064.8 grams, 2.35 pounds); the 2K11 is 8.56 inches long (21.74 cm) and weighs about 38.5 to 40.9 ounces in 9mm (1,091.5 to 1,159.5 grams). Both hold 17+1 rounds of 9mm.
- 5.4-inch barrel: the Staccato XL, the longest common 2011. It is 9.1 inches long overall (23.11 cm), 5.9 inches tall (14.99 cm), 1.5 inches wide (3.81 cm), and weighs 38 ounces (1,077.3 grams, 2.38 pounds). It holds 17+1 rounds of 9mm.
The gap between the shortest 2011 (the 7.1-inch CS) and the longest (the 9.1-inch XL) is exactly 2 inches.
How Much Does a 2011 Pistol Weigh?
A 2011 pistol weighs about 23 to 41 ounces (652 to 1,160 grams) unloaded, or about 1.44 to 2.56 pounds: compact models use a light aluminum frame, full-size models a heavier steel frame.
By model, unloaded: Staccato CS 23 ounces (652 grams), Staccato C2 25 ounces (708.7 grams), Staccato P 33 ounces (935.5 grams), Staccato XC 37.56 ounces (1,064.8 grams), Staccato XL 38 ounces (1,077.3 grams), and Kimber 2K11 about 38.5 to 40.9 ounces in 9mm (1,091.5 to 1,159.5 grams) depending on configuration, and 40.1 ounces (1,136.8 grams) in .45 ACP.
To picture it, a Staccato P at 33 ounces weighs about the same as two 16-ounce bottles of water, and a Staccato XC at 37.56 ounces weighs a little more than three 12-ounce cans of soda. A loaded 17-round magazine adds roughly 10 ounces, so a ready-to-shoot Staccato P is about 43 ounces, or 2.69 pounds.
That weight is the trade-off: a polymer pistol like a Glock 19 weighs about 23.6 ounces unloaded, so a steel-frame 2011 is roughly 10 ounces heavier — weight shooters accept because the extra steel soaks up recoil and keeps the muzzle flat.
What Is a 2011 Pistol?
A 2011 is a 1911-style pistol with a modular, two-piece frame and a double-stack magazine, designed by gunsmith Virgil Tripp and engineer Sandy Strayer in the early 1990s. They filed the patent for the frame-and-handgrip assembly on July 8, 1992, and US Patent No. 5,293,708 was issued on March 15, 1994. Their company, Strayer-Tripp International — better known as STI — built the 2011 for competition shooters who wanted the 1911’s trigger with far more ammunition. The patent expired in 2016, opening the design to other makers, and STI rebranded itself as Staccato in 2020.
The name “2011” is not a year, and today it is a Staccato trademark — which is why other makers call their pistols “double-stack 1911s” instead.
The key idea is the modular frame. A classic 1911 has a one-piece metal frame, and only the grip panels can be changed. A 2011 splits the frame into two pieces: a metal upper subframe that holds the slide rails and trigger, and a separate grip module — usually polymer, sometimes aluminum — that can be removed and swapped. That grip module is what makes the double-stack magazine possible: the magazine is wider, so the grip is wider too, but the polymer module keeps it from feeling oversized. You can spot a 2011 by the small screw on or near the trigger guard that holds the two grip halves together.
The 2011 stayed a competition gun for about 25 years. Then Staccato shifted it toward duty use, and in 2025 Kimber launched the 2K11, taking the design fully mainstream.
How Big Is the 9mm Cartridge?
Most 2011 pistols are chambered in 9mm Luger (9x19mm). Its standard SAAMI dimensions are:
- Bullet diameter: 0.355 inches (9.02 mm)
- Case length: 0.754 inches (19.15 mm)
- Overall cartridge length: 1.169 inches maximum (29.69 mm)
The 9mm cartridge is small enough that 17 fit in a 2011 magazine, yet powerful enough for duty use. The classic 1911’s .45 ACP is bigger in every dimension — 0.451-inch bullet (11.46 mm), 0.898-inch case (22.81 mm), 1.275-inch overall length (32.39 mm) — which is why a single-stack 1911 magazine holds only 7 rounds.
The Kimber 2K11 also comes in .45 ACP at 13+1 — still 6 more rounds than a classic 7+1 1911.
2011 vs 1911: Same Trigger, Different Grip
A 2011 and a 1911 look like close relatives, and they are: the 2011 keeps the 1911’s single-action trigger, grip safety, thumb safety, and many internal parts. But they differ in the ways that matter most: capacity, width, weight, and modularity.
| Feature | 2011 (Staccato P) | 1911 (Government Model) |
|---|---|---|
| Overall length | 8.1 in (20.57 cm) | 8.5 in (21.59 cm) |
| Barrel length | 4.4 in (11.18 cm) | 5.0 in (12.70 cm) |
| Height | 5.9 in (14.99 cm) | 5.25 in (13.34 cm) |
| Width | 1.5 in (3.81 cm) | 1.25 in (3.18 cm) |
| Weight (unloaded) | 33 oz (935.5 g) | 39 oz (1,105.6 g) |
| Capacity | 17+1 (9mm) | 7+1 (.45 ACP) |
| Frame | Two-piece, modular | One-piece, solid |
| Grip | Double-stack, wider | Single-stack, slimmer |
The most surprising number is the length. The Staccato P, with its shorter 4.4-inch barrel, is 0.4 inches shorter overall than the classic 1911 Government, even though it holds 10 more rounds. The 2011 is also 0.65 inches taller, because its grip is longer to hold the double-stack magazine.
The width is where you feel the difference: a 2011 grip is 1.5 inches wide against the 1911’s 1.25 inches — that quarter inch is the price of 10 extra rounds. The 2011 is also 6 ounces lighter than the all-steel 1911 Government, because the P pairs a steel frame with a polymer grip module.
The modularity is the deeper difference. On a 1911, only the grip panels come off. On a 2011, the whole grip module unbolts, so a shooter can swap grip sizes or replace a damaged grip without touching the serialized frame. That is the feature Tripp and Strayer patented in 1994, and it is still what makes a 2011 a 2011 rather than just a wide 1911.
Everyday Size Comparisons: How Long Is a 2011 Pistol Really?
US Dollar Bill
A US dollar bill is 6.14 inches long (15.60 cm) and 2.61 inches wide (6.63 cm). A Staccato P at 8.1 inches is 1.96 inches longer than a dollar bill (about 32 percent), and the 9.1-inch Staccato XL is 2.96 inches longer (about 48 percent). In height, a full-size 2011 stands 5.9 inches tall — 2.26 times the bill’s 2.61-inch width.
iPhone 18 Pro Max
An iPhone 18 Pro Max is 6.43 inches long (163.4 mm). A Staccato P at 8.1 inches is 1.67 inches longer (about 26 percent) — it would stick out about a thumb’s length past each end. The compact Staccato CS at 7.1 inches is only 0.67 inches longer than the phone.
Standard #2 Pencil
A standard unsharpened #2 pencil is 7.5 inches long (19.05 cm). The compact Staccato CS at 7.1 inches is 0.4 inches shorter than a pencil — the only common 2011 that fits inside a pencil’s length — while the C2 at 7.5 inches is exactly as long as one. The P at 8.1 inches is 0.6 inches longer, and the XL at 9.1 inches is 1.6 inches longer.
DVD Case
A standard DVD case is 7.5 inches tall (19.05 cm) and 5.3 inches wide. A Staccato P at 8.1 inches is 0.6 inches longer than a DVD case is tall, and at 5.9 inches high, 0.6 inches taller than the case is wide.
Sheet of Letter Paper
A sheet of US Letter paper is 11 inches long (27.94 cm) and 8.5 inches wide (21.59 cm). The longest 2011, the 9.1-inch XL, is 1.9 inches shorter than the long edge (about 83 percent of a sheet), and a P at 8.1 inches is 0.4 inches shorter than the paper’s 8.5-inch short edge.
Frequently Asked Questions
How long is a 2011 pistol?
A full-size 2011 like the Staccato P is 8.1 inches long (20.57 cm) with a 4.4-inch barrel. Across the popular models, a 2011 measures 7.1 to 9.1 inches long (18.03 to 23.11 cm): the CS is 7.1 inches, the P is 8.1 inches, the XC is 8.7 inches, and the XL is 9.1 inches.
How is a 2011 different from a 1911?
A 2011 is a 1911-style pistol with a modular, two-piece frame and a double-stack magazine. The classic 1911 has a one-piece metal frame and a single-stack magazine holding 7+1 rounds of .45 ACP. A 2011 splits the frame into a metal upper subframe and a removable grip module, making room for a double-stack magazine holding 17+1 rounds of 9mm. It keeps the 1911’s single-action trigger, grip safety and thumb safety, but its grip is 0.25 inches wider (1.5 inches against 1.25 inches). You can spot a 2011 by the small screw on or near the trigger guard.
What is the smallest 2011 pistol?
The smallest common 2011 is the Staccato CS: a 3.5-inch barrel (8.89 cm), 7.1 inches long overall (18.03 cm), 5.4 inches tall (13.72 cm), and 23 ounces (652 grams). It holds 15+1 rounds of 9mm. At 7.1 inches it is 0.4 inches shorter than a standard #2 pencil.
How many rounds does a 2011 hold?
A full-size 2011 in 9mm holds 17+1 rounds with a standard magazine, or 20+1 with an extended magazine — the P, XC and XL all ship with 17-round magazines, and the Kimber 2K11 holds 17+1 or 20+1 in 9mm. Compact models hold less: the C2 holds 16+1 and the CS holds 15+1. In .45 ACP, the 2K11 holds 13+1. A classic single-stack 1911 holds only 7+1, so a full-size 2011 carries 10 more rounds than the pistol it is based on.
Conclusion
A 2011 pistol is 7.1 to 9.1 inches long (18.03 to 23.11 cm), depending on the model. The most popular one, the Staccato P, is 8.1 inches long (20.57 cm) with a 4.4-inch barrel and weighs 33 ounces (935.5 grams) — about 2 inches longer than a dollar bill — yet it holds 17+1 rounds of 9mm, ten more than the classic 1911 it is based on. The 2011’s real trick is not its length but its frame: a modular, two-piece design patented in 1994 that fits a double-stack magazine into a 1911-style pistol. If you want the 1911’s trigger with modern capacity, the 2011 earns its size.
