One and Done
Head on first one broke off......in five to eight dry fires.
It's OK but not really......
Ordered a 50 pack, price was good. On the range with a student, doing a malfunction drill. First time using a Glock 19 Gen 5, extractor failed to grab the dummy round and extract it, eject it. Got home, tired in my M92FS and they extracted fine, but I need absolute training reliability....... These may work for some training purposes, but for Type 1,2,3 malfunction drills, I will go back to a metal case based snap cap or dummy round. Good news is that Brownells return process is as good as Amazon!!! Easy to send back.
Won't feed properly
While these dummy rounds are super cheap, they're unfortunately not very usable. Trying to feed these into a High Standard 22 was impossible, the ridges / dimples from the plastic molding process causes the rounds to get stuck on each other when fed from a magazine. Unlike a real 22 cartridge, the outer casing is not smooth (nor is the tip of the bullet smooth). This seems it would cause all sort of issues, not specific to the handgun I tried. For 22LR, it seems the solid aluminum trainers would be a far better alternative, even if more expensive.
May be ok for Glocks and M&P not 1911
I used these for a Dept transition course to the 1911. I had previously used them to train with my M&P 45. When used with the 1911, the rim of the case would break off. Not a big deal at first, until a piece of plastic jammed up my Colt Rail Gun and caused a trip to the Dept armorer to get the gun apart.
