Maybe you can help me Mac, I know your company does a lot of work on Guardians. I've had one for a couple of months now and It has trouble with most of the types of ammo I've tried in it (I've tried seven different brands). Most of the rounds from various manufacturers I have tried simply will not go all the way into the chamber. The old-style, non-nickel-plated case Speer Gold Dot ammo are the only rounds I have found that will consistently fit into its chamber(The new nickel-plated case Gold Dots don't fit). The chamber appears to be machined too small. Is this a common problem with the Guardian? I have also been wanting to get the Novak night sights installed on it, but I do not want to wait to send the pistol in until NAA starts doing the custom work and I don't want to have to send it to two different places. Would you guys charge me much to take care of this problem if I sent the gun to you to have the night sites installed? Thanks...Eric@GlockTalk
