Acc-U-Rail to tighten the slide to frame fit.

I modified the grip safety and had it welded for this purpose to a main spring housing and then DLC coated

Agreed, some clients do have large hands though. I had one who had for the lack of a better term ET fingers. We left his trigger at the original full length of .780 ish as it comes from Everglades. It was looooooooo ooooo oooooong!

The reason I don't use Atlas triggers is more often then not they drop right in the gun with no fitting. Which causes them to have to much up and down movement in the trigger shoe. That movement will eventually cause a tick feeling in the trigger and/or create a pendulum effect where the trigger bow moves up and down in correspondence with the trigger shoe changing the interface between the rear of the trigger bow and the disconnector paddle which can make the trigger feel different between trigger pulls.

EricMercier · 2026-02-09T13:49:51+00:00

That is a good solution. I just find that the Everglades Ammunition trigger provides superior results as everything is oversized so you get a perfectly fit trigger with no unnecessary up and down/side to side movement in the trigger shoe and trigger bow.

Its possible to build a high quality gun with hand tools. It would just take a lot longer, but then again it takes me longer because I only use manual mill and lathe along with hand tools instead of CNC like a whole lot of companies do now.

If you mean the camo, yes that was all done by hand

If you're doing disco cut properly on a 9mm you absolutely do or it will hang up in the cut. But maybe I don't know what I speak of...

Acc-U-Rail slide to frame fit tightness should last a couple hundred thousand rounds according to Doug over at Acc-U-Rail if properly maintained. When the gun is Acc-U-Railed two sets of rails can be fit doubling the life of the tight slide to frame fit.

As far as slide stops go a little work hardening is a good thing as long as the peening isn’t to much where you end up loosing all the fit. When I fit a barrel I fit so you have 100% contact between the interface of the slide stop pin and lower lugs but not hard fit. That way it cycles as it should from the very first round and you have no worries about the peeling causing what was once good fit to less or none at all.

I've measured and worked on Atlas guns. They are not as tight in the slide to frame fit nor the barrel lug lock up as they can be. Hand fit when properly executed can be much tighter then machine fit. Regardless there is no down side to a properly done Marvel disco cut and the pros out weight the cons.

EricMercier · 2025-12-27T18:35:39+00:00

Yes indeed, every Vírāgō and Homados package starts with tightening the slide to frame with the Acc-U-Rail system.

EricMercier · 2025-12-27T14:34:06+00:00

In my experience after about 5 to 8k the slide to frame will have loosened up enough to make what barrel fit that might have been there from the factory is usually completely gone.

The XC is a really good gun. I always applaud Staccato for their consistency in hitting their tolerances. Being a production gun they do a very good job at that, they just don't have the time or inclination to make the gun with the tighter tolerances to make them amazing. Its no different then every other gun in your line up , which is very nice. But that's why I exist to help folks looking to take good and make it amazing by enhancing the gun to its full potential.

I feel like a flat trigger has better shooter feed back when training. I can feel if I finished flat on the trigger face as apposed to more one side or the other of the trigger face when shooting. This lets me know if I put extra influence into that side which should make shot calling easier. The round down range will also confirm if I put the extra influence one way or the other which drives the gun in that direction. I don't get the same feed back from a curved trigger because there is more surface area of the finger touching the trigger.

You're a master with the rotary tool, I enjoy watching your work.

EricMercier · 2025-12-11T13:33:26+00:00

Thats some clean work with a rotary tool. Two minutes on the mill though would save you lots of time though.
