My buddy is 85 years old and we still shoot a couple of times a week.
A few weeks ago I got a call from a LGS telling me that they just got in something that I'd be interested in. Sammy and I are at the shooting bench when the call comes in, so we saddle up and head to town.
While I'm doing the paperwork on a nice P228 he is pestering a clerk into showing him another pistol from the display case.
I look over and Sammy is holding a P365xl with a RDO on the slide. The clerk is putting the hard sell on the optics but Sammy has this look on his face like he's talking to a Martian. But he likes the way the pistol feels in his hand...so he buys it.
Sammy is one of the best shots that I've had the pleasure of knowing. He can throw a coke can into the air and put three rounds through it before it hits the ground. He does this stunt with a .45acp 1911 shooting from the hip AFTER drawing from a holster.
We get back out to his ranch and he asks me to "take that damn thing off my gun". The RDO goes back in the box. His first attempt at the coke can yields two out of three shots hitting the can....No rear sites on the gun. But remember, he is shooting from the hip after a draw. When the can is tossed his pistol is still in the holster.
It took about a week to get the rear sight and plate to clean up the gaping scar left on the slide from the RDO removal.
This type of shooting is called point shooting. It's something that you have to invest time and training to master. It's not a gimmick that's for sale.
Shooting is a mighty big tent with room for all types of folks. Some do bullseye, competition, rifle, black powder, and defensive. Lots of room for lots of different shooters. None more better or more valid than the next. Just different.
I've always focused on defensive shooting and CCW. In that vane, I've removed iron sights on all sorts of "classic" pistols to eliminate snags on the draw.
So, if you're a RDO fanboi.....I challenge you. Holster your pistol and toss a coke can into the air. Three shots, using your fancy sights.....OK, this is a rhetorical question....I get that YOUR range probably won't let you draw from a holster, much less toss coke cans in the air.
