cases will likely require minor fitting. My first
thought was to have Apex fit one of the former
to my gun. At the time they were offering free
fitting. However, the cost of shipping the gun
both ways is expensive and including the price of
the barrel was more than I could afford.
I contemplated doing this myself, as I've fit
more than a few 1911 barrels, but the M&P is
a new animal to me. After seeing where and
how material needed to be removed, I wasn't
confident that I could do it without screwing it
up. If too much is removed, it would be a sloppy
fit-saying goodbye to match-grade accuracy.
However, I figured that if they could fit the
barrel to my slide, I could handle fitting the
barrel to the frame. Shipping the slide was
cheap compared to shipping the gun, making
this a viable project. Apex was happy to oblige
me and before I knew it the new barrel and my
slide arrived.
The barrel was superbly fit to the slide. When
locked in the slide, there was no front-to-back or
side-to-side movement at the breech. And, the
barrel slid up into place without effort. At the
muzzle end, there was no movement or slop in
any direction. This is as good as it gets, folks.
Now the question was about fitting the
bottom lock-up surface to my frame. This

material must be removed evenly for a proper
fit. The bottom lock-up surface pad on the dropin barrels is narrower than on the gunsmith-fit
barrels, requiring less work for a good fit. (Apex
might change the size of the pad in the future.)
I spoke with an Apex representative about
fitting the bottom lock-up surface and was told
that tolerances were tight and that some guns
didn't require any material to be removed-
that it would drop-in with a snug fit. Well, that
turned out to describe my situation perfectly.
With the barrel in place, the slide would
go all the way forward with a slight hint of
resistance in the last few millimeters of travel
when slowly hand cycled. When cycling the
slide quickly, no resistance was evident.
According to Apex, ideally, when the slide
is slowly, manually allowed to go forward, it
should stop just short of full battery. It should
require a little more pressure to be manually

The S&W and Apex chambers appear to have the
same case support.

The Apex barrel's feed ramp is narrower than the
factory barrel.

no fitting of the bottom lock-up surface by the author.
