Our new Stealths arrived last week and today the SO and I finally got them to the range. These are both stock R9s with John's curved extensions and we both preferred using the extensions. We used ammo we had on hand - UMC - and as you might expect, we both had several FTFs usually cleared by pulling the trigger again. In one case she had to eject a round which I reracked and fired. In addition I had 2 FTEs with mine though it was early and I may have limp wristed it. None of this was unexpected with the UMC and both guns were quite accurate at 7 yards. We both thought the recoil was very manageable but i will need to change up my grip as the trigger guard smacks the knuckle on my trigger finger and took off a little skin which cut my session short. There was one unusual event - at one point her slide locked closed. The weapon was cool, she inserted the mag and was unable to rack the slide. I popped the mag out and was still unable to rack it. After putzing around a bit, suddenly I was able to rack it again and she fired a few more mags without incident. Any ideas on that??
