Due to how expensive the gun is and that there are just about zero parts, I will never put anything remotely hot in it. I know it was "designed" for the NORMA load, but still, I have plenty of other 10mm's that I can put underwood in and have zero fear of issues, or breaking something not replaceable.

I have shot a few of the ARMSCOR, which is a fairly weak load. But really that is about all I want to push. It will get mostly PPU, which is almost 40S&W power. It lets me "experience" the gun enough.

For super power stuff I shoot the Glocks or S&W 610

MJohn was that your video on FB looking up as you shot?  It looked to be running quite well if it were...

Yep. That's me. It is running nice.

Interesting. I didn't know the Bren took 1911 springs.

So I asked an acquaintance who owns two BTs about recoil springs and he said he was pretty sure 1911 springs work. So I took the recoil spring out of my Delta Elite and put it in. Sure enough it fit. So I shot a magazine of low power PPU through it using the Delta Elite spring and it worked fine. So I ordered the Wilson Combat 22# which is what Wilson Combat uses in their 10mm 1911's. I shot 60 rounds of PPU and 10 of ARMSCOR and they all worked great. It was nice having the heavy spring. It feels more solid.

Was the Wilson Recoil Spring for the 1911 a flat wire spring?

Nope. Round

Three mags. All are working well except one does not activate the slide stop. But I am happy that I can fully load the Galco Miami Classic up
I also put a Wilson Combat 22# 1911 recoil spring in and it is shooting great with it. The factory spring felt very weak.

So Mjohn 3006 do I dare ask what one of your 10s do you like the most??

That's like asking which kid is your favorite.
