I took my new to me LCP (374-XXXXX) to the range today and experienced many failures to feed. It looks like the rounds are impacting the steel insert in the frame BEFORE hitting the feedramp. You can see the brass/copper on the insert in the crappy pic below. A quick Googling shows this is not an uncommon problem. Before I call Ruger, has anyone here had a similar problem and if so, how did you solve it?
11/20/2014: Called Ruger and got an RMA. Shipped off to Prescott.
11/24/2014: Arrived in Prescott.
11/26/2014: Got a shipment notification this afternoon from Ruger, I immediately called to find out what they did. It sounds like I'm getting pretty much a new gun, they replaced the slide, barrel, all internals, and worked the frame insert. After replacing all the parts, they test fired 100 24 rounds with no malfunctions.
12/01/2014: Received my LCP back with the following information:
Items Replaced: Barrel, Guide Rod, Recoil Spring Inner & Outer, Slide Assembly
Items Repaired: Frame Insert, Lubricated Slide Rails
After repair, pistol was function fired 24 rounds of Black Hills 100gr FMJ without malfunction.
They machined some relief into the edge of the frame insert where the rounds were striking. I'll take her to the range tomorrow and update.
12/12/2014: Finally got to the range and the LCP was flawless through 50 rounds. Considering I couldn't get through a single magazine without a failure, I'll call 50 in a row a win! I still want to run another 100-200 through it before I feel comfortable carrying it.
