Try them in YOUR firearms, working up small quans and slowly. You will come to your own conclusion, one that works for you.
Lots of us have the same experience as BillD. Me included.I've used tens of thousands of SRPs in 9mm, .38, .40 and .45 with no issues on hammer fired guns.
At least 100K. Lots of folks who reload for .223 use SRP's exclusively for all their loads.
Never had a failure.
Most of mine has been CCI SRP.Lots of us have the same experience as BillD. Me included.
But it's wise to recognize WalterGC's trouble (post #7) with hard primer cups. Rifle and magnum primers have harder cups to withstand greater pressure. Walter's experience is valuable to recognize.
I think that may be quite significant. I had very frequent failures to fire from the batch I accidently loaded with three Glocks and an M&P. They are striker-fired. I did not have a hammer-fired pistol with me that day. That may be the difference that could be a deal breaker if you use striker-fired pistols a lot.with no issues on hammer fired guns..
Sure wished I'd testfired a few, before I did that batch of 5000!!!Lots of us have the same experience as BillD. Me included.

Get a 9mm AR15 carbine for those hard primers. Full hammer strike will ignite them. Or an open bolt full auto. That'll work.[aQUOTE]
Had one of our local gendarmes try some in his 9mm AR-type subgun. Lots of misfires.
