I've finally gone through over 2800+ rounds through my Glock G40.
2200 Bayou Bullet moly coated 200 gr with 9.4 gr of Blue Dot, equal mix of CCI and S&B Primers.
200 Hornady 200 gr XTP's with 9.4 gr of Blue Dot and CCI Primers
100 Hornady 1080 gr XTP's with 9.4 gr of Blue Dot and CCI Primers
100 Montana moly coated 200 gr WFN with 9.0 gr of Blue Dot and CCI Primers
20 rd of Buffalo Bore 180 gr JHP
40 rd of Hornady 180 gr JHP
100 rd of Underwood 220 gr hard cast
50 rd of Underwood 200 gr hard cast
20 rd of Underwood 180 gr XTP
Edited:
Add another 2200 bayou Bullets for 5k+
Here's my observations:
The underwood and buffalo bore had a little more recoil than my loads but nothing over the top. Very comparable practice load imo.
The moly coated bullets fouled about equal to jacketed for the first 100 rds.
Started with 200 pieces of Starline brass for the moly stuff and now have 143 pieces. Have yet to find cracks or loose pockets in the brass. This is loading to the hornady book max of 9.4 gr of blue dot.
Starline brass has shrank just slightly. I feel it on the crimp die but have not measured it.
The montana WFN's need to be seated deeper to feed in a glock mag unless you only load 5 rounds at a time. It starts binding with 1.25" OAL after about the 5th rd.
10mm makes bowling pins fly a hell of a lot further than 9mm.
You get funny looks at an action pistol match when the first round goes off.
Great report! Thank you. Would you happen to have any velocities for these loads?
Other than the magazine binding issues due to COAL, any other malfunctions experienced?
Great report. Love my Glocks!
I've had 3 bad primer strikes with the first batch of S&B primers. I attribute that to not having the primer seated right as they ignited on a second hit. They are harder than the CCI's and I wasn't squeezing it as hard with the primer tool.
In the first few hundred rounds after changing to steel sights the front wobbled loose but I cleaned it up with acetone and applied blue loktite generously and it hasn't moved since. Don't skimp on the loktite.
1 quib from the underwood 200 gr xtp. Knocked it right out. No damage to the barrel.
A few of the underwood 220 cast bulged the case. I did not clean the barrel prior to firing it so I ran a brush and a few patches through and shot the rest of the ammo and they did not buldge. Primers were starting to show signs but no bulge afterwards.
Did manage to load a cartridge in the mag backwards while I was jaw jacking at the range and that royally jammed things up.
I will be replacing the RSA at 5k rds just to be on the safe side.
No idea on the velocities as I don't have a chrony.
Nice report! I admittedly am not a Glock guy, but that long slide G40 and the G41 intgue me!!!
Thanks for taking the time to write this up!
Thanks for the report MA.

Yes, good report...Barely broke in...carry on! :D
How has the accuracy been with the loads this pistol likes?
Good. I'm loading for velocity so no real accuracy testing yet.
Placed second in tonight's bowling pin match with it. Turns out there were two other shooters with G40's and they talked about bringing them out next match as well.

Great report! Thanks!
Another 2200 through the barrel. Still going strong.

What steal sights are you using? Looking at options, the factory sights are crap for any kind of distance shooting

I use AmeriGlo's for the time being.
Front: lGL-212-165-125-GR-C
Rear: GL-414
This combo gives me a high viz 0.125" front with 30 thousandths of light between the front and rears.

Thanks for the report. It gives me confidence that my G40 will hold up for the long haul.
