I too, just had the good fortune of purchasing a brand new R9S Stealth Elite from a very reputable dealer in South Florida. Took the pup to my local range, and by golly - the first round wouldn't detonate! Then the third, then the fifth, and so on...It got so scary, because I waited an appropriate length of time, before unchambering the non-fired round, and sometimes there would be smoke inside there, along with what looked like a half detonated live round.
I had the owner of the gun shop - very experienced with Rohrbaugh, etc. shoot some different ammo - self defense rounds and the same things were happening to them. I ultimately packed it in for the day, as I thought by continuing, I would be risking a major injury either to myself, or the gun.
Before I ask for advice - the gun was cleaned, lubricated, different kinds of "correct" ammo was used ( so it's not the ammo), different magazines were used (so it's not the magazines)...it just seemed like the the firing pin was very light on some of these rounds. What do you all think and suggest I do? Also possible is that the rounds weren't being chambered and seating properly?
Any help would be sincerely appreciated. I am going back to the place I purchased tomorrow for his response as well.
