Home Forums Hunting & Shooting Handguns Glock 40. 10mm

I have searched a little bit for what load those sirus scouts carry in their 10mms, but didn’t find anything.

I'm running a G40 with a Leupold Dot. It shoots Double Tap's 200-220 hardcast well. I have only shot it on paper out to 50 yards and its accurate. I have no issues banging a 10" steel target at 100 yards with it.

Works just fine in mine.

Same here. 7” KKM, polished trigger mechanism by Glock trainer armorer, RMR with Trijicon suppressor sights to co-witness the RMR thru the glass. Easier, at least for me, to find red dot faster.

Sent frame to Sinners Mass in San Antonio to remove finger grooves, checker the grip. Sorta slims it down some. Google them.

Out of town. Will post photo next week. To me, the Glock kicks less than 1911 variants, although they have better triggers. Glock holds more rounds. The synthetic frame must absorb recoil better than steel. And the fatter grip may also contribute to less perceived recoil. Actually a rather pleasant pistol to shoot considering the power level.

Bullet type never dictates spring rate needed .

That’s said the mass of the slide especially with an optic added , and the dual recoil spring setup , lets the g40 work well as supplied from the with even the hottest off the shelf stuff.

I appreciate the help. When I get it, I think I will run it as is. If it's not broke, I won't fix it.

If there’s a weak spot, it’s the trigger.

My bud, a LEO firearms instructor, said to position a Glock trigger at the first joint, not the tip of the finger like shooting a 1911. Seems to work.

too me, the 20 makes more sense. I am not sure there is a big accuracy gain with the 40, and the 20 is already a big gun. I just don't see it unless you have to have a red dot.

Little accuracy gain between the 20 and 40. Big difference in velocity. Enough that with a stock barrel my 20 won’t meet Colorado big game minimums of 550ftlbs at 50 yards. The G40 will.

And the MOS version is slotted for RMR and such.

The drop in 7” KKM barrel pushes the envelope even more. Big gun, hunting vs carry.

I really like mine. I swapped a Zev trigger kit and installed a Vortex Razor I bought here on the forum and had a local guy tweak the grip (I detest finger grooves). I have only loaded the 180 gr XTP over AA9 and it does shoot very well. My middle son had one and found this one cheap as a factory refurb that I could not pass up.

After seeing what Sinners Mass in San Antonio did with your frame, sent mine for identical treatment. Just got it back and put gun together. I like the way it feels. Thanks for the inspiration.

I hate finger grooves, too. Like it without them. Those guys do great work, are nice to work with.

So far 180 XTP’s are the most accurate in the factory barrel over a stiff load of Longshot. Haven’t shot the 7” KKM barrel. Plan to get hard cast. Also have Cowboy Action surplus 180 gr .38-40 soft lead to try. The KKM should handle those better than the polygonal factory barrel.

Will try 200’s, XTP’s and hard cast.

Here's mine with RMR and 7" KKM, tall Trijicon suppressor irons to cowitness the RMR. I get a full view of the irons thru the RMR glass.

Is your Vortex reflex sight low enough for high Trijicons to co-witness? To me, that set up seems to make finding the red dot faster. It is said as one gets used to the reflex sight, the red dot is found quicker. I'm not there yet, like the high irons to help find the red dot.

Those guys do good work. The grip seems slimmer without those finger grooves. And they cut thumb rests. I told them to do exactly what they did for you, sent them a printed picture from your post.

Thanks for the inspiration.

DF,not trying to tell you what to do but I think you're going to want to run those soft lead bullets at cowboy action speed or you might have a mess on your hands. I just wouldn't shoot soft lead, liking easy cleaning and velocity more.

Glad you are pleased with their work. Super folks indeed.

The KKM has conventional, not polygonal rifling. I would think it would handle soft lead pretty well.

When it quits raining, may need to get some loaded and see.
