I purchased this for my Colt Authorities Pocketlite .380. It wasn't a tight in shape so I soaked it and remolded it for the Colt. Then I extra two or three stitches near the result in guard. The result is undoubtedly an sufficiently limited fit. Good deal for the value. https://smithwessonmp15-22magazin76296.blogaritma.com/31183320/aero-precision-m4-e1-things-to-know-before-you-buy
