I had the chance to get the .380 to the range yesterday for its second go around, and I'm happy to report that things were vastly improved.
This time the pistol was freshly cleaned and lubed, and 177 rounds went downrange. 40 rounds of Hydra Shok, 100 rounds of American Eagle FMJ and the rest Gold Dots.
I did have two malfunctions, both with the FHS; one FTE at round 37, and on FTF right at the end of the session (which was a pain to clear). 100 rounds of the AE was absolutely flawless as were the Gold Dots.
I was very encouraged by the session as the little pistol shot beautifully and accurately. I think I will be switching my main carry load to the Speer Gold Dots as they seem to work very well in just about every pistol I own.
I was so pleased with the Rohrbaugh that I've made the decision to acquire an R9 as soon as I can. I've been pocket carrying the .380 for a couple of weeks now, and I love the smooth, snag-free profile of these pistols, as well as the ergonomics. It has really grown on me, and I think it's time to add its big brother to the fold.
By contrast my Kahr P380 continued to have problems, with 8 more premature slide lock-backs over 40 rounds. I'm convinced that slide locks on small pistols like these is a bad idea. Rohrbaugh and Seecamp have the right idea.
Thanks to all for the help earlier in this thread.
