Question: Will they fit a sig sauer stx?
Document: These look great on the 1911 and have almost a grip tape texture to them for maximum grip. Some fitting was required for Sig Sauer 1911 for the ambi to function properly.
Great fit and the surface has good grip. Very nice grips fro the price.
The thumb cutout made choosing these a no brainer. They fit perfectly and my hands just feel natural with these grips.
fit perfectly for gun and feels good holing it not slippery have a firm grip wanted a change and it was a perfect fit
Perfect fit in my ria 1911 feels great looks good just what you expect from a magpul product everyone loves them that has seen them
Awesome, looks great on my Ruger SR 1911, great fit and function, love the cut out for ease of magazine release....
Can't beat it for the price. Excellent surface grip, and the recess for the mag release makes for even faster reloads. Put these on a Ruger 1911 CMD and fit perfectly.
I picked these up for my RIA 1911 GI. They fit perfectly, and I was able to use the screws that came on the gun already. The grip is good, not the best, but the build quality if solid and for the price it's hard to go wrong.
This grip fit my Springfield Loaded perfectly. I like the recess on the left grip for better mag release. The only reason it's not 5 stars is that I'd hoped it would be rubberized. Instead, it's hard plastic. Beyond that, it's Magpul. What's not to like?
Awesome 1911 grips! These fit me like a glove especially if you have smaller hands like me. I installed them on my ATI Commander size 1911 and would now consider this for my everyday carry piece. The grips do have a smaller profile and make it easier to carry on the hip/
Answer: yes
