That was done at the factory. It was definite overkill, but I had no problems with the grips on the first one. Maybe this was an extra-strong batch.
Although, I'm using blue Loctite on threads more often, and red, too. I've had grip screws starting to loosen after only a few hundred rounds fired.
Getting back to working with my newer handguns, here are the first-fire results from the Steyr M9, and the FNX-40.
The performance of the M9 with the Remington "disruptor" ammo (I know it's a Klingon term, but that's what keeps coming into my head) caused me a series rethinking of the defensive role of the right ammo with the right handgun. The Steyr, to me, is a nicer-handling, nicer-shooting version of a Glock. I'm trying to buy a new Steyr CxA in both 9mm and 40S&W.
The FNX-40 shows the results of the first magazine of standard 155gr .40S&W ball, although I'm looking for more "disruptor" in that caliber, too. My other .40s just struck me as meh, but with this handgun, they turned themselves into an easy-shooting, and fairly accurate combination. I admire the dual safety/decocker function, and what I suspect is a vey short trigger reset. I had no idea I could do so well with any .40S&W handgun. I might buy an FNX-9 just to round out the collection, if I ever see one. Magazine prices on FNs have doubled to about $45 in the last couple of months, but I managed to get a good supply of .40s already. The FNX-45 is new on the market, and I can't find any spare mags yet. The only reason I scored the .45 was because it was a special order, and the guy who ordered it backed out of the deal, so I bought it before it was put in the display case.
Now if I could just get some quality trigger time on the range, but that's in short supply on most days, with time limited to only 30 minutes, and that's after taking a number and waiting an hour. A lot of those new gun owners are on the range now, and are suddenly realizing that the box of ammo they bought with their new weapon just went downrange, and they need to think about buying a practical amount for the next time.
And I'm waiting for UPS to deliver my SiG P220 short-reset trigger kit. The SiG already gives near-instinctive double-taps already. Just a little twitch of the trigger finger as the round goes off, and you get another one. :)
