Apex 5" confusion

Recommended Posts

Good morning, 

 

 

I'm considering an Apex 5" barrel for my M&P 9mm.  Folks here on the forum seem to like the gunsmith fit barrel best, but it appears only the conversion barrel and one of the threaded barrels are gunsmith fit, the remainder are semi fit.

Was there once a 5" barrel that was gunsmith fit, or when I see gunsmith fit mentioned it's referring to the semi fit barrel?

 

Thank you in advance for any help!

 

All my best, 

Rob

I don’t know what kind of accuracy you are looking for but my semi fit for the pro shoots 1-1.5” at 25yds all day...

When they first came out you had the Semi-drop in (SDI) and the gunsmith barrels.

 

SDI barrels work in the vast majority of guns. I fit one to mine and it tightened groups from 8” to 2.5” without any load development to optimize ammo to barrel.

 

Sometimes one is very, very far out and needs the gunsmith fit barrel. This one has a great deal more material on the pads that need trimmed to fit, and is intended to be fitted with a milling machine.

 

The SDI is much closer to dropping in and can be fit with files and patience by hand.

Good morning, guys!

 

Thanks!!  Saab,  I would be thrilled with groups twice that size!  (Which I can't shoot anyway! 😉)  I wasn't sure which barrel was the one folks were using that they were happy with, but it sounds like the currently made semi-gunsmith fit will be perfect once it is available.

 

MemphisMechanic, thanks for the info!  I was wondering if that was the case, since I did notice Brownells showed a gunsmith fit barrel that was 5" and not threaded, but it said discontinued.  Hopefully mine is one of the not too far out ones....but then again, if I didn't have bad luck, I wouldn't have any luck at all!  Once they are available again, I'll order one up.  I've fitted a few 1911 barrels, and this seems to be a bit easier except for the muzzle end where I'd have to remove material only in two spots.  The 1911 is easier for a guy like me because I can just measure my barrel and order a bushing of the right ID., and turn the outside down.  We'll see how it goes!

 

Thanks so much for the info and taking the time to share it, guys.  Very much appreciated.

 

All my best,

Rob

With latest version I did not need to remove any material from muzzle end of barrel, only trim the part contacting breech face and the pad contacting locking block. 

After fitting 1911 barrels, thisbwill be a walk in the park for you, just watch the videos by Apex. They recommend a hard fit, where initially you need a few lbs of pressure on rear of slide to complete return to battery. Slide closes fine during live fire.

This is exactly how my gunsmith fit barrel was set up.  (2016 ish 5" 9mm Apex Gunsmith fit barrel) It's tight and needs a bit of a push on the rear of the slide to get into battery.  She shoots clover leaves if I do my part.

I seems the M&P's are pretty variable in fit/tolerances.  Work necessary to fit a barrel on one won't be required on the next pistol right beside it on the shelf.

 

For mine, I only had to remove metal from the rear where the two tabs contact the slide.  Slow/steady with lots of wiping/checking before I finished up.

 

Made a big difference in the groups.  It seems to especially like the Winchester 124 grian FMJ Nato ammo.

 

For what it's worth, on my 5" 2.0 FDE the Apex barrel made a much bigger improvement in the group size than the Apex trigger set up.  I like the trigger a lot, super nice, but the barrel had a bigger effect on shrinking the groups, for me.

Check out the barrels manufacturer. Just because Brownells discontinued it doesn't mean that the manufacturer did too. Or the mfg may have a couple of them left.

Thanks, everyone!  Much appreciated. 

 

Anachronism, that's a good suggestion...thanks!  I did just check but it seems only a conversion barrel and a threaded barrel are gunsmith fit.

 

Based on the comments and help here, the semi-drop in will be great!

 

Thanks, everyone.   I appreciate the input and the time you took to help me!

 

All my best,

Rob

I have the gunsmith fit 5" apex barrel it was quiet and improvement over the stock barrel grouping wise. It cost me a lot more to get it fitted locally. I'm not sure there was much advantage over a semi drop in.

Good morning,

 

I purchased the Apex Semi drop in, and was quite pleased that I didn't have to mess with the front of the barrel.  Only had to fit the hood and as you state, mpom, it was a walk in the park.

 

It certainly shoots much better now.  I suspect that had the pad needed a bit of filing, it would have been even better, but I'm extremely happy with the results.  Now, off to get a new front sight!

 

Thanks to everyone for the input.  I'm glad I kept it and put the barrel in rather than buying a 5" bbl M2.0.
