S&W CSX Micro 1911

New Smith and Wesson CSX Makes The Micro 1911 Much Better

The CSX is a new spin on the micro 1911, which might make the format a little more relevant. Here's what you need to know…

S&W CSX: Double-Stack, Single Action

The micro 1911 is nothing new; Colt originated the concept with the Mustang back in 1983, although that gun was chambered in .380 ACP and was never a strong seller. The format had a resurgence with guns like the Sig Sauer P238 and Kimber Micro, which were then scaled up for the 9mm cartridge.

Springfield Armory, followed suit with the 911 series of pistols, offered in .380 and 9mm.

The S&W CSX is a micro 1911 in 9mm, but has the additional party piece of a double-stack magazine.

The standard capacity is 10+1 with the flush-fit magazine, and the gun also comes with a 12+1 extended magazine.

The slide has front and rear cocking serrations with dovetailed three-dot sights. The frame is not railed, but it wouldn't be able to mount many micro lights anyway. The controls are ambidextrous, with right- and left-side slide releases and ambi thumb safety levers. The slide is steel, with an aluminum frame with a polymer grip insert.

Just like other micro 1911s, the grip safety has been omitted. The trigger has a safety tab, adding an additional layer of passive safety. The beavertail is longer than most other micro 1911s, which should give the shooter a better firing grip.

Smith & Wesson CSX Specifications

Smith & Wesson CSX specifications fall close to the Shield Plus in most respects. It is a sub/micro-compact with a scaled-down 2011/Staccato-style magazine. The specifications, according to TTAG and Guns.com, are as follows:

Barrel Length


Overall length







19.5 oz (unloaded)





All but identical to the S&W Shield Plus, just with a different firing system. 

More Is Sure To Come For The S&W CSX…

If there's any constant about S&W's product lineup, it's that optional extras and upgraded models are always sure to follow, so this is probably not the only version of the S&W CSX we're sure to see. Hade one to guess, an optics-ready model, a Performance Center edition, and some other optional features are likely going to be added soon.

Perhaps they'll be announced at SHOT Show 2022, or perhaps they'll be announced when ready.

But what do you think? Is this the new carry pistol of your dreams? Do you think this gun makes the micro 1911 a little more relevant…or do you think John Browning's finest work is best in its original format?
