I'd just get the KKM. Besides the pitch differences, the KKM barrel's threaded area is machined flat on the sides to mate with the set screws that keep the compensator in place.

I’ve got a pair of 19.4 guns with the KKM, and having experienced them, I’m quite happy and do not feel a need to try other designs.
Per the PF Code of Conduct, I have a commercial interest in the StreakTM product as sold by Ammo, Inc.
And the KKM screws are large enough to actually do their job plus not strip out when you tighten them down.

In general what is everyone running for recoil springs? Any difference with and without the x300u? My last minute hesitation is that I don't want to suddenly make a reliable gun conditionally reliable only for certain ammo, and I also often carry without a WML but also carry with one.
Stock RSA in mine and while it's a new build with less than 500 rds down the pipe it hasn't choked yet... HST 124 +P, Am Eagle 124 ball, Federal 115 ball.
This is my second Roland build; I had previously sent a GEN4 to ATEi but eventually moved on from it. I revisited the concept with a G45 MOS and this has become my favorite pistol. In my experience, these run very well with Federal ammunition; I've found the comp doesn't like weaker Blazer ammunition (whether Blazer Brass or the aluminum cased stuff). I've vetted it with G2 for carry (though eventually I'd like to try it with some 135gr. +P Hornady Critical Duty). I use a stock RSA; I've run it often without the WML and haven't noticed a difference.

15lb flat wire (gen 3 style) on a steel rod. with a 4lb striker spring
The reliability issues are overblown. You just have to balance recoil springs and striker springs.
It works without the x300 but weaponlight are mandatory so.
I’ve had exactly one light strike. It’s no factor.
With a stock RSA it tracks down in recoil. Yuck....

Regarding the lighter RSA's that many use in a Roland.... What about the whole Return To Battery test? The one where you point the empty pistol skyward, pin the trigger back, and then slowly cycle the slide to see if it will return fully to battery. And if it doesn't then the recoil spring is too weak and may cause out of battery ignitions.
My two comped G19's will only pass that test with stock RSA's... Even a 16lb spring will keep the slide from fully seating. Is this because I did not install a lower weight striker spring to compensate or am I missing other data?
Reduced power striker spring.
The slide doesn’t cycle slowly— it cycles very quickly. So slowly letting a slide go forward tests imo, absolutely nothing
Also - and I don’t mean this like it sounds -
When I want to know how my gun functions...I grab a bucket of ammo and go shoot it. I’ve found that a much cleaner test than standing in my living room pointing my gun up and holding back the trigger (2 actions that never crossed paths for me )
