Hi Guy! I understand. I'm wondering if the geometry of the ramp is different between 45ACP and 38 Super?

Hi all. I did a search but didn't find anything useful. I have a alloy non-ramped 1911 frame for 45ACP and want to run a 38 Super upper. One option I like is to run a non-ramped 38Super barrel on the frame to minimize frame work. I'm hoping the shape of the 45 ACP ramp area will reliably feed 38Super ammo without modification. Anyone have any experience with this? If the 45 ACP ramp area won't work, what reshaping is required to reliably feed the 38 Super rounds in a non-ramped 38 Super 1911? Thanks

No. That rule did not change in the latest update.

A pic of the underside of the replacement slide might provide some clues.

Thanks! I better adjust my gear and get to practice!

Why? You think it will get too heated? My original question hasn't been answered yet.

The USPSA newsletter just announced rule changes. "In the February 2021 USPSA Board of Directors Meeting, a few rules were updated..." My question is when do these go into effect? Immediately? Or not until the rule book is updated and re-released? Here are the specific changes to the rules: o App. D2-D7, Item 14 – Changed to ‘Yes, must be functional’o App. D4, D5, D7, Item 12 – Removed reference to App. E3o App. D4, D5, D7, Item 20, 4th bullet point – Removed ‘Magazines may not be retained through magnetic means.’o App. E3 – Deleted bottom diagram showing equipment position in relation to hip boneso App. D5, Item 18 – Maximum single stack weight with empty mag increased from 43 oz. to 45 oz.

I run mine with a Springco recoil management Guide rod and 10 LB spring.

As best I can measure: I measure the lid inside diameter as 0.680" (looks like my caliper tip is all the way in the grove). Measuring the O-ring directly is difficult because its so flexible. Laying on a flat surface I get: O-ring ID = 0.525" O-ring thickness (dia) = 0.025" O-ring OD = 0.680" I hope this helps. Sig will probably send you some new ones.

Absolutely agree. Plus they are so easy to use with very simple controls. I also have the Shooting Chrony. It works well but I hate the cryptic controls ( push Fu 3 time, stand on head, release, what for flash, push twice, ...). PITA.

To answer your question, you stop and tell the range officer. They will assist you in making sure the gun is safe. As Kraj said, its a DQ if the competitor tries to clear the squib during the course of fire.

I heard back from GGP. Al said they saw a few problems with some of the original slides but not much after that. He fixed me up with a new V1 or V2 of my choice.

Anyone have any, or heard of any, issues with the P320 GGP version 1 slide cracking(splitting)? I bought one and used it last season. Put about 5k rounds on it. I noticed it was split starting from the rear of one of the side lightening cuts going straight back for about an inch. I can see a faint split on the inside as well. I contacted GGP and sent pictures. I’m waiting to hear back from them. I did a web search but didn’t find any hits. Just checking to see if it’s a know issue or just a fluke.

I was thinking breech face insert like Infinity. But I don’t think anyone offers a service to replace or modify the breech face of a slide.

I completely understand. Whatever ammo you are able to get, I recommend checking accuracy so you know how it performs. Best of luck with the house and Happy New Year!

To add more about the accuracy question. I had a similar experience as Rowdy. I also shoot CO and I realized my trigger control was terrible at speed and have had success in correcting that and improving my at-speed accuracy. But I had also noticed an inherent accuracy issue. After bench testing my reloads (i.e., using a bench-supported grip) at 20 yrds, I learned that there was a HUGE difference in accuracy among my competition loads. I have two main competition reloads (because of the supply shortage). Of course this is possible with any gun and is not specific to the X5. I knew accuracy would be different among the load and gun combinations but I had no idea it could be so much! The worst combination was with 147gn Xtreme RN copper plated at about 900 fps out of my X5. I was getting 5 to 6 inch groups at 20 yrds which translates to 6 to 7 inches at 25 yrds and is totally unacceptable! And yes, I checked it multiple times to be sure. However, with the same gun, I get 2" groups at 20 yrds (2.5" at 25 yrds) with 135gn coated RN at about 980 fps (OAL for both is 1.145"). That's not great accuracy but it is acceptable for a stock gun. When I repeated the process with my RXP, I get 2" groups at 20 yrds with both loads. Bottom Line: Bench test the accuracy of your load with your gun and check it periodically. I hope this helps.

The rule book states - "Modular frames in the 1911 style". If a so called modular "2011" frame, which operates with single or double stack feeding device, isn't a modular 1911 style, then I don't know what is. Sure would be nice if the definitions were clear.

Correct. That language is in the March 2020 V2 rule book. Again I ask, what is an example of a " Modular frames in the 1911 style" if a so called "2011 frame" is not allowed. We are talking about the frame, not the grip.

March 2020 V2 is the latest.

Very confusing. So what is an example of a " Modular frames in the 1911 style" ? All the modular frames I can think of are called "2011 frames" even though that has nothing to do with the size of the feeding device.

After re-reading the rules, a 2011 frame is of modular "1911 style" and is allowed. The restrictions are on the magazines not the grip. So it looks like any grip that will accept a 1911 magazine that you can attach to a 2011 frame is allowed. Is that your understanding?

I interpret "Modular frames in the 1911 style, which use traditional single stack 1911 magazines" would rule out a widebody grip, period. If you look at the specs for the Staccato C, the grip is of Single Stack design.

Here it is. D5 Special Conditions Frames must be metal. Modular frames in the 1911 style, which use traditional single stack 1911 magazines, are allowed. No wide body magazines, including those adapted to feed in a single column, may be used.

This may be moot anyway. I think for single stack the frame has to be metal. Checking now.

The outside grip width is 1" (consistent with single stacks). So I think it was designed for a single stack mag. Its not a double stack grip modified to accept a single stack mag.
