I carry my CZ75 Compact every day. Just finished mowing the yard about an hour ago in all this heat/humidity.
Back in about 1983 or 84 I was carrying a M29 S&W, two double speed loader pouches (4 speedloaders), my radio, mace, a double handcuff case with two pairs of the S&W hardened handcuffs and a night stick ring (seldom carried the night stick but wanted the loop/ring on my belt in case I did grab it from the car) for 8 or 9 hours a day, if I worked over it could be 12 to 16 hrs.
One night my buddy on graveyard shift asked me how much the rig weighed and I told him I had no idea. We went to one of the offices that had a postal scale and I pulled the belt/gear/keepers off my pants belt and set it all on the scale. Just over 13 lbs. I had no idea it weighed that much.
Carry it and you will become used to it.
