Yeah the internet can sometimes be like a bunch of gossips gathered around a campfire yammerng on with authority about stuff with which they have no personal experience. Sure the Mark 23 wasn't likely as big a hit with certain US govt. assets. Who cares? I think anyone that buys a piece of equipment because that's what the covert ops guys use has more present problems than grip size or trigger pull; same goes for folks who accuse another of being that sort without actual knowlege.
I put the grip sleeve on because my palms are big (not hairy though
) and I like the swell the Hogue provides. Heaven help anyone that needs to remove it though. hehe.
I think the OP will enjoy the Mark 23 if he gets it. Most folks who get it, do.
