Glad to hear you got it running, and that it is shooting well for you both.

Another 140 rounds today. 3 ftl with the stingers. I have noticed when loading the mags the spring is sometimes getting stuck, and or the bullet is staying up and not dropping down for the next one. I’m going to look a little closer at the mags see if I can correct both those issues.

I had a sig mosquito. It would only cycle mini mag reliably. I sold it and bought a SR-22. It will cycle anything.

I've always had good luck with CCI Blazer.

It might be worth a try. Cheaper than Stingers, which is very good too.
