BASE772

I just received six PAE base pads today as well. Very, very nice. But the version I got weights 1.4 oz so with the stainless steel guide rod I'm going to be close on weight.

The 12.5# ISMI is the spring I settled on for my 147 loads. Way lighter than a 13# Wolff for sure. The 14# ISMI was close but still felt slightly heavy.

Just ordered some PAE pads. Very nice.

Thanks for the detailed reply Alma.

At $45 each I don't feel too bad about getting aggressive with texturing and other projects on the P320 since I know that if it doesn't work or looks bad that I can toss it and put on a new grip frame module. Cutting this high on the beavertail does require backfilling with epoxy below the FCU. I have also started playing more with adding weight inside the mag well between the "rails" My 3 Gun grip has about an ounce of #8 lead shot epoxied back there. Not saying these are things that you need to do by any means but because that lower isn't serialized the P320 platform is ideal for tinkering. Is that a .375 base pad on the 320 on the right. Springer has the .250 and .375. I assume the .375 base pad still fits in the box. Trying to decide between the .250 and .375 right now.

For Production can't you take out some material from the magwell as long as the opening is no more the a 1/4" bigger than the outside dimensions of the magazine?

I had my 320 sent directly to Robert Burke so I will never know what the original trigger pull was. But it's great now. I don't have a trigger pull gauge so I can't measure it. Will find someone and post the trigger pull weight later. When the buzzer goes off it feels like 3# which is what I set my 1911's too. Sweet! It's no 1911 trigger but is a very easy trigger to shoot. Only had my 320 a week and shot our local Pro Am with it yesterday. By the end of the match I was shooting times faster than with my beloved 1911/2011's. And as Alma was speaking about striker force the 320 is a beast! ( I have a thread about this) . I'm having about a 2% (guess) rate on Winchester SPP's where the firing pin will slightly pierce the primer. Puts a big old dent in the primers. Light strikes not going to happen on this gun. Never shot Production before and I'm excited to go down that road with the 320. On a bother topic, does only one else feel that the 320 is one of the smoothest feeding guns?

No. But still waiting on the 320 base pads from them. Ordered them 4-1-15. And. After a range session today I like the 12.5 ISMI spring the best with my minor loads. Had to cut almost two coils off it for the slide to make it all the way back. Didn't have to cut any on the 14# ISMI 1911 spring. I also decided I like the large grip over he medium grip.

I like the ISMI 14# spring better than the 13# Wolff. Seems a little lighter.

I've always liked the ISMI springs better. I've got a 12.5# and 14# ISMI on hand now to try. I ran 14# ISMI in both my 2011 Limited guns so may try the 12.5 first for 9mm minor. The Wolff springs seem to have a slightly larger ID than the ISMI. The ISMI have very little to no play with the Gray Guns Fat guide rod.

I do like WST for minor .45 loads too. 3.9 gr WST under a SNS cast 230 gr loaded to 1.265 gives me 658 fps so 151 PF out of my Trojan. Put in a 12# recoil spring and it feels like 9mm minor.

Thanks for the replys. Guess I'll start with a 13#.

Just curious what weight and how many coils you cut off if needed. I should be getting my 320 from Robert Burke soon. I've got a Gray Guns fat guide rod and 12# to 15# Wolff 1911 recoil springs. Been seeing the 13# spring mentioned a lot. Will be shooting 147 grain minor loads. Just looking for a good place to start. Thanks

I'm waiting on a Dawson rear now. Ordered a 115 rear notch which is custom for now so it can take up to four weeks.

Thanks for the replys. Could be the quality of the metal in the primer cup too. They are cheap but go bang every time. I'll just have to wait and see if my full size 9mm 320 does the same thing when it come in. Robert Burke has it now.

Anyone have their P320 pierce soft primers? My daughters Carry 320 will pierce the soft Mag-tech primers about 1 in every 10 or so. Won't do it with CCI or Winchester. Haven't tried Federal primers. They are 9mm minor loads. The cases in the pic were all the same load, just different primers. Mag-tech on the left and the two CCI on the right.

I agree. My 1911 with a 17lb mainspring eats up small rifle primers.

Nice. Bullseye is my favorite powder for .45 Major and 9mm minor. Haven't seen it around here in a year and a half.

I'll own a .357 Sig one day. The Carry Nightmare 1911 in .357 sig would be awesome.

3.2 gr. Bullseye under a SNS 147 FP @ 1.135 gets me 133 PF out of a P226.

I just use SPP in them. Work great.

The SNS no lube ring 230 are awesome. Best profile of the coated .45 that I like. Bought 9000 of them and only have 3000 left. No problems or leading.

I did when I got home. Got two on the way.

I'd like to buy one from Bruce but the web sight won't let me.

It's likely similar. I will measure tonight.They close to the same? .325" Humm,.... You think that .013 smaller size of the Springer would make a difference?
