I thought I would add more data to this thread vs. the one I topped yesterday, since this one seems to have the best running conversation on the FTF malfunction I had the other day.
To summarize: Friday, at a normal square range visit to confirm some parts swaps, I shot the G48 again. At the time, the gun had been milled by Primary Machine for a 507k, and had an SCD, a Ghost connector, and an Overwatch Precision PolyDAT trigger shoe/trigger bar.
I had pre-loaded a mag of 10 once-chambered Speer Gold Dot 124+p. The first round was chambered, I pressed the trigger and got a 'click'. I cycled the action, shot one more round, then round 3 had a fail to feed:
Magazine used was ID number R-8. I compared R-8 with three other mags last night, and could not tell any difference, at all, visually. (my calipers are in storage so I could not measure the feed lips).
Forward plan is to try an abbreviated @
Joe Mac 'three round' test with some AE124, Federal HST147, and the GD 124+p. Ammo being what it is, I plan to shoot 12 rounds of each across four mags. I mean it ain't cheap but this is my carry gun and I want to have some confidence in it. I appreciate my choice of G48 brought with it a gun with a smaller envelope of timing/reliability than a double stack Glock, and it might be ammo sensitive. But that's where I am.
(Another possibility is the RSA; I have almost 1K through at this point, so out of an abundance of caution I've ordered a new assembly. $17 isn't going to break the bank.)
And of course if no more malfunctions show up, what then? One of my favorite sayings is
absence of evidence is not evidence of absence. But for sure I will have more confidence if these all run ok. And if mag R-8 bobbles, I'll mark it as a range use only and throw it in the extra pile.
