All I am wanting to practice reloads with my Beretta 92A1 and other handguns and possibly rifles. Well I have always been taught you aren't supposed to drop the slide on a handgun without a round ready to be chambered, especially on something like a 1911 which can be quite bad for the extractor. So I am looking for some durable snap caps or dummy rounds that would allow me to safely drop the slide to simulate a reload. So far I have used Tipton and A-Zoom aluminum snap caps and they shed fragments of material after a few chamberings. Does anyone make a more durable snap cap? I am thinking a proper brass cased dummy round would work well but would imagine bullet setback would become a big problem after a few chamberings. Does anyone have a remedy for this? Can you recommend a snap cap or dummy round that will be best for use in semi-automatic pistols for closing on an open slide for the purpose of practicing reloads? Thanks!
