Nearly all the aftermarket slide stops say for .45Auto use only. Will they work in a 10mm. ? or is there a difference in certain dimensions ? I want to upgrade to a heavy duty for my DW Razorback. Thanks
Colt is the only maker of which I know has a slide stop specifically for 10mm. The part that varies is the length of the arm that protrudes into the magazine well and gets pressed upward by the follower on an empty magazine. The .38S/9mm slide stops have a longer arm as the follower is generally more narrow than that of a .45. The 10mm is a little thinner so there is a possibility that the follower may not engage a .45 slide stop. As Don pointed out, a .45 slide stop will probably work. Worse case scenario is that you have to buy a .38 Super slide stop and file the arm slightly so that it ends up somewhere between .45 length and .38 Super length.
