I just purchased my first GP: An XCalibur MK12.
Now, granted, I haven't been able to make it to the range yet, but I've gotta say this right off the bat: I'm completely blown away by the quality of this gun. The fit and finish is absolutely exceptional (I was especially impressed by the polish on the internals), the ergonomics are perfect, the SA trigger is insane (better than any of the Shadow 2's I tested while shopping around, IMHO), the slide action is buttery smooth, the lockup is tight as heck...I mean I could just go on and on about this gun. As an engineer by profession, I am completely stunned by the quality of the design, the execution, and the actual production quality of this firearm.
Anyways, now that I've finished with my unbridled gushing (sorry about that, just had to do it!), I do have a couple questions about recoil springs:
My XCalibur came with three recoil springs (one in the gun and two out), but they all looked the same: cylindrical black wire types, with 23 coils (like this one: https://grandpower.eagleimportsinc.com/grandpower/shop/parts/x-calibur-parts/recoil-spring-light). The one in the gun was about 1/3" shorter than the others, but I image that's just the result of it being compressed for so long.
Do these guns ship with 3 Light recoil springs?
If these are light recoil springs, are they appropriate for standard power ammunition (i.e. not +p or +p+), or should I sub in one of these: https://grandpower.eagleimportsinc.com/grandpower/shop/parts/x-calibur-parts/recoil-spring?
Which recoil spring weight would guarantee the best performance and lifespan of the firearm with standard loads?
Is there anywhere I could find a wider range of recoil spring weights for the X-Calibur (i.e. besides the eagle imports site)?
Oh, and I'll be sure to post an actual range report as soon as I manage to do some shooting (hopefully in the next few days).
