Big guns conceal much better than you would expect. I can carry a full sized 1911 and conceal it fairly easily. To me, the size of the weapon has less to do with it than the all-up weight of the gun AND all the ammo it contains AND the extra magazines and their ammo. That's what's going to pull your pants down around your ankles... Not the size.

According to the Glock website, the G30 weighs 24 oz unloaded with a standard capacity of 10+1 rounds. The G36 weighs 22.11 oz unloaded with a capacity of 6+1 rounds. My Kimber Stainless Ultra Carry weighs 25 oz unloaded with an empty magazine (Glock doesn't specify if the unloaded weight includes the magazine weight or not) with a capacity of 7+1 rounds. My Kimber disappears from my consciousness once it is strapped on, and I don't notice the weight at all. I have it on right now with two backup magazines, and the weight is fine.

The point is that, since both Glock models weigh within a couple of ounces of the Kimber, and within a couple of rounds of capacity of it either way, either pistol should be no problem to carry and conceal for you, as long as you have a comfortable holster and a good gun belt.
