SI MAGWELL

Will the SI Magwell fit my pistol?

As a general rule of thumb, the SI Magwell fits very nicely on frames with pre-beveled magazine wells. If your pistol was manufactured to original USGI specs, the SI Magwell will fit. The SI Magwell does NOT work on arched mainspring housings. Please refer to our Fit Guide below.

 

SPRINGFIELD

Range Officer Government, Ronin, Vickers, Mil-Spec, TRP, Emissary, Garrison, etc.

Please select the FULL-SIZE SI Magwell. The SI Magwell will work very well on the above models with little to no fitting or blending.


Range Officer Compact

Please select the COMPACT SI Magwell. The SI Magwell will work very well on the above models with little to no fitting or blending.

 

EMP

Unfortunately, Springfield EMP frames are often out-of-spec and we cannot guarantee the SI Magwell will install without fitting or blending.

 


DAN WESSON
Heritage, Specialist, Valor, Vigil, Pointman 45, Kodiak, Razorback, Vigil Commander

Please select the FULL-SIZE SI Magwell. The SI Magwell will work very well on the above models with little to no fitting or blending.


Vigil CCO, Specialist Commander

Please select the COMPACT SI Magwell. The SI Magwell will work very well on the above models with little to no fitting or blending.

 

Guardian, ECP

Unfortunately, Guardian and ECP frames are manufactured with a bobbed mainspring housing and will not be compatible with our SI Magwell.

 


COLT

Pistols manufactured prior to 2018 do not have pre-beveled frames and will require minor fitting for installation.

 

 

ROCK ISLAND
Unfortunately, Rock Island frames are often out-of-spec and we cannot guarantee the SI Magwell will install without fitting or blending.

 


LES BAER

Unfortunately, Les Baer frames are often out-of-spec and we cannot guarantee the SI Magwell will install without fitting or blending.

 


KIMBER

Stainless II, Custom II, Stainless Raptor II, Rapide

The SI Magwell works very well on most Kimber frames with little to no fitting or blending.


Compact CDP

The grip safety on Series 2 Kimbers need to swing outward enough to allow the plunger to retract back into the frame. Some light filing on the relevant contact areas will do the trick. Often it is the front part of the mainspring housing "ears", as that surface is what usually acts as a stop to the rearward swing of the grip safety.

 


SIG SAUER

STX Full Size, Emperor Scorpion Full Size, TACOPS Full Size, Spartan II Full Size, Equinox

Please select the FULL-SIZE SI Magwell. The SI Magwell will work very well on the above models with little to no fitting or blending.

Emperor Scorpion Fastback

Unfortunately, Scorpion Fastback frames are often out-of-spec and we cannot guarantee the SI Magwell will install without fitting or blending.

 

BUL Armory

Our Full Size SI Magwell will fit most BUL Armory with little fitting and blending. 

 

 STI

Spartan, etc. 

Please select the FULL-SIZE SI Magwell. The SI Magwell will work very well on the above models with little to no fitting or blending.

 

 

Will the SI Magwell fit with slim grips? 

The SI Magwell will fit with standard grips and will stick out slightly with slim grips. We highly recommend pairing VZ 'magwell' or 'flat bottomed' grips with our SI Magwell.
