Any updates? I have what is essentially a 9mm STI Eagle only the slide was tri-topped. Rear dovetail is a Bomar cut. I looked on DSC’s website, and they did say the Atlas GW optic cut is compatible with slides already cut with the Bomar/LPA dovetail. Anybody do this and have pics? Being that this is for a comp gun, rear sight (or front for that matter) is not needed IMO.

Following. I was just on TwoSee’s website. Anybody have any experience with their 2C 1911 Direct Mill cut for the SRO on a 1911/2011 slide that does not require a mounting plate? Cuts the optic pocket low enough that they had to do a step cut on the top of the slide to clear the SRO’s hood. https://www.instagram.com/p/CodOaAOS6GG/

I use the Wheeler Fat Wrench (analogue) at home and have a basic Fixit kit in my range bag. Much better than guessing. Seems like 12-15 inch pounds is a pretty common torque setting for the size of red dot optic mounting screws, but I recall reading somewhere that if you’re using lock-tite you should back off a pound or two since the lock-tite acts like lube and you can over-tighten the screw as a result.

The bottom picture is how Fire 4 Effect ‘solved’ the problem of the Trijicon’s mounting footprint being slightly too wide for the Shadow 2. They milled in two pockets for the ‘pillars’ as you call them which are dovetailed in and further secured with cross screws. I believe the intent was to provide more ‘meat’ for the mounting screws to attach to. I have two guns they did the milling for and have not had any issues. Sadly Fire 4 Effect went out of business in 2022. But I think I saw something online that said Impact Machine has taken over F4E’s mounting method (it may have been patented).

Not all, but quite a few who also compete in centerfire PRS like to have their rimfire rifle mimic or be close to their centerfire rifle. Ergos are the same and you have access to much more after-market support and parts interchangeability (chassis, stocks, triggers, barrels). That kind of puts you in the Bergara, Vudoo, or RimX camp however, and plenty of people are doing quite well with their CZ 457s or Tikkas and both are popular enough that you have good after-market support, albeit not as robust as a Rem700 pattern barreled-action. I looked at the Ruger, but the limited after-market options for upgrades made me shy away from it. NRL22 allows semi-autos and every now and then I see somebody show up with a tricked out 10/22 but bolt action is way more common. NRL22 rules (and PRS as well) require the bolt to be open and back when changing positions on a stage. For semi-auto you have to put it on safe and also say out loud “On Safe” so the RO can hear you. Not a big deal once you get used to it.

I like nice things as well, but truth be told I think you can be competitive with a factory CZ, Bergara, or Tikka provided you put in some work to find the right load the gun likes, practice a bunch shooting from non-belly prone positions, and with a minimal investment in gear. I got started with a CZ 455, added a weighted Arca rail so it balanced when sitting on a bag on a barricade, bungeed on a dope card holder to my scope, basic Harris bipod that I already owned, experimented with different size/shaped sandbags for positional shooting, and a used Kestrel I got from a friend to calculate my holds out to 300+ yards. That was enough to get me started. I didn’t worry about range finders for the first year because the distances were always known (plus other people had LRF’s), and I also got to experiment with using their bags and plate systems until I figured out what worked best for me. Then as I shot more matches I started upgrading my gear. First on the list was a better scope with the features I wanted: close parallax, lot of internal elevational travel, 10-12 MILS per rotation in the turret bc in .22 world you have to dial A LOT to get out to 300 and 400 yds, good FOV, a zero stop, and a reticle with a Christmas tree for the stages where you have to hold elevation and wind. My next big upgrade was a tripod for rear support and also to support my binos when spotting. I also use it for dryfire and live fire practice without needing all the props you typically see at a match. Then I bought a Kestrel 5700 Elite to replace the old kestrel since the newer ones have better features, and also got a LRF bino that Bluetoothed to my new Kestrel so all I had to do was range the target and my dope would pop up in the display. That’s a big time saver if you ever shoot a NRL Hunter match. The Sig LRF binos do have onboard AB calculator so I guess in theory you could skip the Kestrel but I trust my Kestrel more than the Sig LRF at this point. I’m at the point now where I feel like the CZ was holding me back so last month I ordered a Vudoo w/ a 22” straight taper Bartlein barrel. My reasoning for the heavy barrel is to make balancing it in the chassis easier and the extra weight is going to help steady the rifle when shooting off a bag in awkward props such as a tank trap, fence post, rocks, etc. It’s a fun game and I’m enjoying shooting 2-3 matches a month in addition to USPSA. Plus it’s nice to be able to buy ammo and not deal with finding all my shot brass and brass prep like I have to do with centerfire rifles.

I would agree. Other than the rifle itself, I use the same gear for the rimfire PRS/NRL22 as I do with centerfire PRS. Both rifles have a full length Arca Swiss rail for mounting bipods and gamer plates.

What caliber do most of the other people at the bowling pin matches shoot?

Coming from the SP-01 Shadow with the extended thumb safeties, I hated them. Ended up adding the DSperman heavier detent springs bc my support hand would sometimes bump the safety one. Ended up switching them out for the flat safeties. When I got the Shadow 2 (this is when CZ shipped them with both the flat and extended safeties) I put the flat ones on right of the bat and left it like that ever since. IMO, when shooting DA/SA guns there’s no need for a thumb safety in our game. Either your gun has the hammer down at make-ready in DA mode or you’re shooting. There’s a few videos online showing the different techniques people use to lower the hammer on a SP-01 or Shadow 2. Might be worth your wife watching them if she hasn’t. Plus if she does this a bunch of times in dry-fire it might make her feel more comfortable.

I had my first Shadow 2 milled for an optic when the max weight limit for CO was 45 oz. At 46-47 oz, the gun was already overweight to begin with for CO (circa 2018 rulebook). But, since I was shooting it in Production at the time and really liked the platform I bit the bullet and had the slide milled for the optic (SRO) and to reduce weight. Came in at 44.1 oz w/ optic and empty mag installed. When I set my second Shadow 2 up for CO, this was AFTER the weight limit was raised so had the option of not doing the slide lightening. However I had the second Shadow 2 milled with the same slide lightening cuts bc I liked how the lighter gun felt and wanted to keep them both the same. The cuts look cool, but they do tend to bite the hand if you rack from the front of the slide. I think I mostly use my optic as a slide racker these days…. I would recommend Fire 4 Effect in TX to do the slide milling for the RMR/SRO footprint but unfortunately they went out of business at the end of 2022.

13 lb mainspring should lite off any primers with stock firing pin and FP spring. If you want to go with the 11.5 lb then a lot of people recommend the extended firing pin and reduced FP spring but quite a few people also report that the 11.5 lb spring works well with the stock firing pin on most primers such as CCI, Federal, etc. Not sure about some of the eastern European or South American inputs. The lowest mainspring is the 8.5 lb. If you go that low, definitely recommend the extended FP and reduced FP spring AND using Federal primers.

This^. If industry was leading this charge it would be more apparent. Everything I’m hearing is the proposed equipment and rulebook changes are member-driven or clean-up based on some things that are no longer deemed needed by the rules committee based on another change that occured in 2021.

No issues with the 12 lb spring in mine. It lights off CCI primers without fail.

IME to get your LTT into the 6&2’s you need to get a lighter mainspring. I want to say the one that comes with their trigger job is a 13 lb mainspring, You need a 12 or 11. It’s the same way with my Shadow 2, with the CGW 13 lb mainsping installed I get around 7 lb DA and 2.5-3 lb SA. But with their 11.5 mainspring it drops to 6&2.
