I am able to run the large diameter spring with CCI Minimags and Blazer. If you can run the larger diameter spring, it helps to make sure the slide is fully returned to battery if the ammo is waxy or dirty. With the small diameter spring, the slide sometimes didn't return fully to battery and caused a light primer strike.

I've had that issue as well Jimbo, I don't think it's ammo related.
The mags can benefit with some smoothing out of the plastic parts and perhaps a bit less spring tension on the follower. I haven't had much time to shoot recently but I did just order some more 12.99 mags to play with.

Right on, I'm going to join the grand power forum today and post up some questions..... there is not much activity there by the looks of it but Canuck is a mod and I would hope that someone else from Grand Power would be able to provide some ideas for tuning.....?
Have you tried reducing the power of the mag spring?

I've done the tuning to my mags. Smoothed out the follower and helper stud, clipped some coils from the mag follower spring. They work great on most ammo, but I have noticed that with some ammo that have a more tapered bullet, I still get the odd round that will fly out (Winchester 333, Remington Bucket-O-Bullets). Anything 40gr round nose feeds great.
I've cut a few coils off a few of the mag springs. The best I've had it work so far is having 7 rounds of CCI AR Tactical with the large recoil spring in place and modified mags. Other ammo or 8+ rounds and it turns into a complete POS. I don't live in New York so I'm not pleased.
Joined the GrandPower forum but my Canadiangunnut name has been auto replaced by Canuck to Can-down.....
Hopefully some of the world wide users of the .22lr's will have something to report as far as mag feeding issues....
I don't think we will see any interaction over there till they all are back from Vegas/Distributor tour
The backordered MecGar mags I had on hold from Brownell's shipped this week too. I don't see it being too big of a job to mod them.
Looks like they already got a hole there for me as a start lol.
So these CZ mags arrived, they will need a fair bit of work on the top, as well as the square cut out for the mag catch.....bleh.
I don't think I will bother, they are really nice mags and I don't want to fck them up...plus I don't really like the gun that much anyway lol.
So I'll either save them until I buy a CZ or Tang, or I'll dump them on the EE.

if someone local is up for work on it with me, I'd be happy to figure out how to cnc the mag catch (and perhaps the top depending on whats needed). Likely wouldn't be any cheaper than factory mags in the end, but at least it mags. Might as well since I'm taking a bunch of metal off a first gen x-trim .22 as well.
Brennan did some really nice machining. He milled the slot in the slide similar to what the new generation X-Trim has, but it only reduced the slide weight from 270g to 265. Not really noticeable difference in performance with different ammo. The Winchester M22 which gave me 8 FTE's with the large recoil spring only gave me 1 FTE. The American Eagle 40gr RN ammo still ran very poorly though, so I'm going to have Brennan do some further lightening of the slide.
Bummer, VanMan. That sucks. I was hoping that slot would help more. My brother has a manual mill at his shop and I was thinking of doing the same thing.
The new gen X-Trim also has one extra vertical slot (each side) in front of the chamber. Tougher to machine to match though.
What are your plans to refinish the exposed metal areas? Something like cerakote will add more weight. Probably not too much, but if fighting for grams is this tough, it sucks to put them back on again.

I'm going to have Brennan mill a cutout in the spring shroud. The metal is thicker there, so I'm hoping it will remove more weight. For the exposed areas, I'm probably just going to do some cold bluing - not too concerned about having it match the color of the barrel.

I put up a DIY post on making the magazines for those interested
