Different Types of Pistols That Can Be Converted

Aug 3, 2020 | Glock

While gun owners may have historically looked to a longer gun when looking for improved accuracy and range, you no longer have to upgrade to a larger, clunkier firearm to see these benefits. With the introduction of handgun conversion kits, there are now a number of different pistols that can be converted.

Handgun conversion kits can help turn a pistol into a more accurate, long-range firearm in just a few seconds. By placing your handgun within the conversion kit assembly, you can then stabilize and fire your weapon like a rifle as opposed to a traditional handgun.

Below, will be a deep dive into various brands and pistols best suited for conversion kits: 


It doesn’t take a gun enthusiast to be familiar with the GLOCK brand. Known, across the world for its exceptional design, engineering, and manufacturing, these handguns are a favorite of civilians and law enforcement alike. 

In business for more than 30 years, Glock can stake claim to the title of “leading global manufacturer of pistols.” The organization has earned this distinction with firearms that satisfy military and law enforcement specifications worldwide.

Synonymous with safety, durability, reliability, and ease of use, GLOCK will continue being a leading industry brand for generations to come.

Military personnel and law officers all over the world trust the GLOCK 17 as their pistol of choice – because it’s designed for professionals. With unparalleled reliability, feather-like weight, and 17-round magazine capacity, this classic model stands the test of time.

The GLOCK 17 9mm Luger pistol provides users with ease-of-use and quickness. However, one of these firearms’ most attractive features is its Safe Action trigger system, which ensures optimal safety.


Compared to the standard sized options, the GLOCK 19 in 9 mm Luger brings tremendous versatility to the table because of its less cumbersome dimensions. 

Conventionally, this pistol is for service purposes but also proves incredibly useful for concealed carrying or as a backup weapon.


In the 19X, the full-size GLOCK 17 frame has been expertly combined with the compact GLOCK 19 slide.

The result? A pistol that’s ideal for any imaginable circumstance.

GLOCK’s 19X possesses the first-ever factory colored slide in the coyote color. It prevents corrosion with an improved NPVD slide coating finish.  

There’s also the GLOCK Marksman Barrel (GMB), no finger grooves, and ambidextrous slide stop levers.

Boasting its lighter weight and a robust, sturdy platform for GLOCK handguns, the MCK Micro Conversion Kit is ideal for the brand. Furthermore, there’s a barrel shroud crafted with aluminum and a polymer body.

There’s no need for any pistol disassembly. All that’s required is placing the pistol into the kit, locking it, and voila! It’d be remiss to forget the right-folding stock arm brace – a feature the heightens concealment.

With 1200 dedicated employees working tirelessly in its top-notch facilities, SIG Sauer is known for constructing the most robust and precise pistols on the market. They’re also world-renowned for rifles, suppressors, optics, ammunition, and airguns.

SIG Sauer P226

This full-sized, service-type pistol shares the P220’s basic design. It differs from the older model in its ability to use higher capacity, staggered-column magazines, instead of the single-column magazines used by its predecessor.

SIG Sauer P229 

The SIG Sauer P229 is a compact pistol with a semi-automatic handgun trigger. It’s also the first of its kind to be able to chamber the 3.57 SIG round.  

Interestingly, the P229 is constructed as a compact version of the staggered-column P226 design. Similar to its predecessor, it’s commonly used for military and law enforcement. 

SIG Sauer P320

As one of the SIG Sauer’s latest offerings, the P320 is highly modular and versatile – adaptable to any mission. It boasts an array of available chamberings and frame sizes that are based on a serialized internal chassis. 

Some of the primary features of this modernized pistol are as follows:

  • Hammerless, striker-fired system
  • Interchangeable grip frame
  • Picatinny rail

For the P320, there’s a Micro Roni Generation 4 called the Micro Conversion Kit that’ll convert the pistol into the ultimate SIG Sauer submachine gun. 

It has an extended stabilizer in standard, which allows users to fire with one-hand, optimizing their overall shooting. Furthermore, a Velcro strap makes for comfortable usage. Lastly, this kit helps improve accuracy up to 200 yards.

With the P226 and P229, the SIG-A1 Sig Sauer Under Barrel Rail connects onto the trigger guard area. It’s also infused with reinforced aluminum to combine durability with its lightweight. The SIG-A1 makes it seamless to connect the handguns to spec rail-mounted embellishments. 

Smith & Wesson

In 1852, Horace Smith and Daniel Baird Wesson became partners to produce a firearm that was able to fire a self-contained cartridge.

Innovation, high quality, and reliability have always been at the forefront of Smith & Wesson’s production and design. With an array of historical contributions to the firearm industry, this iconic organization has continued to lead and trailblaze for nearly 170 years.

Smith & Wesson M&P 9

This striker-fired, semi-automatic handgun possesses a 17+1 standard capacity. Its frame is built out of Zytel polymer, and it has a stainless-steel chassis for extra support. 

This model also features a low bore axis, offsetting muzzle flip. This feature is also conducive to faster follow-up shots.

Smith & Wesson M&P 2.0

This semi-automatic handgun is a new direction for Smith & Wesson, who usually focuses on traditional steel and alloy-framed handguns. Unlike the iconic firearms company’s previous efforts, the M&P 2.0 is a polymer-frame, striker-fired pistol.

Like the other pistols, this model is used by law enforcement and military personnel. Its highlights are its lighter weight, high capacity magazine, and a crisp trigger pull.

Similar to the other conversion kits suggested in this blog, there is a Micro Roni Generation 4 made specifically for these Smith & Wesson models. 

Meaning, there’s no pistol disassembly required – all that’s needed is attaching and locking. And there’s ambidextrous, quick, and straightforward handling. Another central feature is the built-in charging handle, which makes for prompter assembly/disassembly.
