This is what I use for 9mm and 40SW. Also works for 45 ACP and other calibers. https://www.maglula.com/product/uplula-9mm-to-45acp

I've loaded different OAL's and haven't had any issues. The Tripp magazines I'm using are the 10/40SW 10 round mags.

I'm using the same magazines and my ammo is loaded to 1.18 too. Only thing I can think of is your springs might be worn out. Maybe stretch the springs out a little to see if it solves the problem. You might want to call or email Virgil at Tripp. I had an issue with my Tripp mags when I first got them and he resolved the issue for me. His number is 512-321-9445 or you can email him at info@trippresearch.com. Hope this helps.

I'm using Federal Magnum small pistol primers on my Carry Optics minor and 40 major loads. Have not noticed any difference.

Plus you can get a plate in case you want to convert it back to irons.

Same happened to me when I bought my SP01 Shadow. Round is too long. I solved the problem by shortening to OAL 1.09. Eventually I sent my barrel to get reamed so I could load longer. Since your running factory ammo you might want to consider getting your barrel reamed.

I have the same R1 Limited and use the MBX magazines, but they are up there in cost. I also use two SPS magazines that work good in the R1 and are about half the cost.

The screws that Trijicon sends are a little over 11mm. I just trimmed mine down to 10mm with a dremmel and everything worked.

These are on SP01 Shadow and posting them for your reference. The first one was done by CZCustoms and the second one was by CGW. Both sit on plates but the one milled by CZCustoms sits much closer to the top of the slide. Advantage with these two companies is your not tied to one RDS. CZCustoms makes a plate with rear sight if you decide to take the optic off and shoot irons. They make them for both SP01 and Shadow 2. Hope this helps.

^^Just to add, the SP01 Shadow does not come with the firing pin block.

Edit: Didn't read that its for 2011

Milled using CZ’s optic plates. .

I’m in a similar situation as you. I love shooting USPSA and IDPA in SS, but my eyes don’t cooperate anymore. After trying different red dot guns at the range, I decided to get the SP01 Shadow, sent them to CZ_custom and had them milled for RDS.

Dawson Precision.

Semi-fit. Very easy to fit using their video.

I put the Apex barrel in mine and the Apex flat trigger. use it in USPSA CO. VERY accurate!

The number for the S&W is 1.

This is what I use. I’ve used it on Sig and Remington 1911’s and an M&P. Ordered it from Amazon.

Not familiar with the Staccato C but probably the ESP division.

What happened with the 10mm mags that made it no good for IPSC? I have 10 round 10mm Tripp magazines that sit flush with the magwell. I ask because I'm doing an IPSC match next month and I also have a Max in 40.

What type of problem?

The SVI trigger dropped right in. Don't remember having to take any material off the top or bottom of the trigger. Make sure you order the Billet Grip Trigger Bow Wide Body. Here's the link for the one I ordered. https://infinity.americommerce.com/p/144-Billet-Grip-Trigger-Bow-Wide-Body.aspx

I have a Sig Max 1911 and a Sig 1911 Traditional and they both have different slide profiles. The Traditional does not fit in the Max RHT holster. I use a 1911 Bladetech holster so I can use one belt setup. The Traditional fits a little loose and I have to tighten the bolts. When I use the Max I tighten the bolts a little more. Not the best option but it works. Other option for me is setting up another holster.

This is my R1. Full disclosure, the first thing I did was installed an EGW ignition kit, changed the trigger and magwell to a Cheely. Changed the front sight too but that was a preference for a thinner sight.

I have one and it’s a great gun. Unfortunately I believe they stopped making them.
