I've got about 15 years with my Glock 20; 16 or 17 years with my Glock 29. They are good for 25-30 yard shoulder shots on feral dogs or eastern coyotes. I wouldn't try to take a deer at more than 20 yards with either.(I would try for a deer with a 6' .357 mag single action at 50 yards). I'm making up my mind on a Glock 40 or a longslide 1911 10mm. Maybe I'll try a longer aftermarket barrel for the Glock 20, but I like to keep my handguns as stock as possible. I don't change things out until they break, changing springs doesn't count.

Bone stock Colt Delta elite at 15 yards, standing, two hand grip, slow fire....

Had a site pusher tool and was centering it up for my eyes.  You can see the previous group covered with black pasties..




That's about six inches.  Tried it off table rest and it isn't much better.

JUST FOR FUN (REAL FUN)  WITH A CALIPER OR BETTER WIPE THE NOSE AROUND CLEANED MEASURE AROUND THE FLAT SURFACE OF BULLET
COMPARE TO INTERNAL BORE
BEFORE BUYING NEXT BOX OF 10'S MEASURE DIAMETER OF BULLET ALONG FLAT WHICH EVER IS LARGER TRY THAT BOX OR IF HE HAS A OPEN BOX
EVERY .1OOO MAKES A DIFFERENCE IF BORE IS OK.
GIVE US THE WORD.

Yep, it looks like sliclee is trying to reference 0.001" or one thousandths of an inch or 1/1000".

Some 10mm firearms actually have bores as small as 0.3990", most are 0.4000", however glocks are known to be 0.4015"-0.4020" in the bore.

For cast bullets it has been shown that 0.0020" over bore provides a better seal and less lead fouling.  With semi autos finding the best bullet size may cause feeding issues in tight chambered firearms, so usually 0.0010" or 0.0015" is what will feed best while still providing a good seal to yield accuracy with reduced fouling.  The blowby with the heat of the powder gases can leave deposits if too small, in addition to the actual smearing as the bullet takes to the rifling if not big enough.  BALANCE

TXCOONDOG has some impressive groups from his RIA 52000 at 25 and 50 yards off a rest

I bought the same pistol, I'm still working on loads for it but I will never have group sizes like him ---If I can shoot 1/2 as well as he does, I'd be happy

I have a Gen 3 Glock 20C I average 1.25"-1.50" at 11 yds, factory barrel, underwood 200 gr. I also have a Barsto smith fit barrel that does the same. Dunno if this gun and I just click or what but the thing is the most accurate firearm I own. I have G19, G22, G 19c, G23C, G22C, HK P30L .40, HK P30 .40, HK P30sk .9mm, USP .40. This G20C puts em all to shame....

Mine shoots minute of bad guy. I don't practice beyond 10 yards. Almost ALL self defense shoo outs are at 21 feet or less and over in less than 5 shots. I know my Glock won't out shoot my Ruger P93DC or a 1911 or hell even the Sig P229 I had. But center mass is all I need.

My G40 and I seem to be doing just over 2" at 50 yards most of the time... There are exceptions, and all of them are my fault.

That is shooting from a solid rest, very solid.

12" steel at 150 yards is no problem at all.

This is a hunting pistol, nothing more... So my practice is at hunting ranges.

Offhand... It's more like 8" at 50 yards.

2.5 moa red dot sight.
