Laser Max and the G20c

[old wanderer]

I was about to install a Laser Max into my G20c. Then I read all the warning about compensated guns will not work correctly. I know when I installed the AeroTec ghost ring tritium sights, I had to go to a +4 to get the gun on point of aim.

I use this for defensive, not as a plinker. I will probably miss my Spingco heavy spring, with DT ammo, but thought it was worth the trade.

I note you say you have a G21c with the Laser Max. Did you send it in for some custom work, just know it is below point of impact, or lucked out and it was perfect right from the box?

One last question, I have a Gen 3 G20c (with the rail), but I have the LMS-1151P kit. What is different about the LMS-1151P FRG?

On the gen 3 glock 20 one was made for Fingergroove frames FGR and one was not. LMS 1151P My 21c was 1/2 inch low from POA to POI at 15 YDS more than acceptable for my uses. I fire all kinkds of loads through mine with no problem and dont need a heavier spring.
