Well, thanks to Irish Guard I'm now the owner of a R9S Stealth, and I put the first 50 rounds through it today. It's running 100% and the recoil is not an issue. What I am struggling with is that the front strap is so short that I can only get one finger fully on it. My ring finger keeps slipping off, and with my middle finger being the only one that gets a decent grip the muzzle flip makes keeping it under control for multiple shots a bit problematic. I measured the front strap at 1.25", and the front straps on my PM9 and P380 are both 1.50". Apparently, my fingers need that extra 1/4". Although I've never been a fan of magazine extensions one may be in order with this gun. I found pics of Yankee2500's curved mag extensions, but not the straight ones. Can anyone post a pic, or point me towards a pic of a straight mag extension?
I tend to bury a gun in my hand and I've noticed the pup has a tendency to railroad track the web of my hand just like my Glocks do.
Overall, a well made piece, but it's going to need a little fine tuning to really work for me. I can certainly see why people enjoy carrying one, as it splits the difference in pocket feel between the P380 and the PM9.
