Many people say most non Underwood non self loaded type 10mm is basically the same ballistics as 40 s&w. What about Georgia Arms 10mm? Good performance or is it weakened 40 s&w also?

I haven't personally tried it. Friends who have, stated that the normal stuff is loaded in the moderate to heavy range, and the +P is full house 10mm. For example the non +P 180's are in the neighborhood of 1100-1200fps, and the +P 180FMJ is around 1300fps. They essentially load their 10mm ammo with Longshot powder which is how you maximize the 10mm's capabilities. If using a G20, I recommend getting a 22lb-24lb recoil spring to keep the breach shut longer. It'll also cause less case bulging and brings your ejected brass within 10yards.
17lbs is standard.
Would Glockmeister sell the 22lb spring? I didn't see it on their site.
