American Rifleman - August 2021 - 57

The mounting systems that optics-ready pistols use can vary
greatly, but Smith & Wesson's line of C.O.R.E. semi-automatics ship
with seven plastic adapter plates and fi ve different screw sets-in
addition to the slide cap that is used when no optic is present.
Leupold's excellent DeltaPoint Pro provides a great
example: Many of the smallest micro red-dots on the
market employ the Shield footprint, but as a " tactical "
MRD built on this pattern, the Leupold is too long for use
aboard some Shield plates and slides cut specifi cally for
smaller " carry " models. This is not a frequent occurrence,
but it does happen. You may note in the following table
that some pistols provide multiple adapter plates for a
particular footprint; given the variance in micro red-dot
size and shape, this is an effort to maximize the number of
optics models compatible with their guns.
Also, because the heights of their housings can differ
quite substantially, even within a given footprint, the
length of the screws needed to secure an MRD to the gun
may also vary. Many OR pistols come with multiple sets of
screws for this reason-S&W C.O.R.E. models, for example,
come with fi ve sets. Potentially confusing the situation even
further: Many pistols use a single set of screws to secure the
optic to the gun, with the plate sandwiched between them,
but some utilize two sets of screws, one to secure the MRD to
the adapter and another to secure the adapter to the fi rearm.
And while it has been my experience that it is usually the
gun side of the pairing that supplies the screws, which makes
sense as it's the thread specifi cation of the holes tapped into
the slide that determines what diameter and pitch of fastener
is needed, a number of optics also include their own.
Be warned, however, that not all OR pistols come with
an assortment of screw sets (some may only come with
one, intended for use with a single MRD model within the
footprint), so maintaining a store of extra screws is a wise
practice. Someone with multiple optics-ready pistols and
multiple micro red-dots may want to consider purchasing
something like Swampfox Optics' Ultimate Red Dot Screw
Pack ($20), a bundle that includes 14 four-screw sets of
various thread pitches and lengths. Not only would this help
ensure that all of your various setups are good to go, but it
would also mean that spares are available for when one of
those tiny suckers inevitably goes fl ying into the ether.
A number of optics-ready pistols feature " suppressorheight "
iron sights, others do not. Some mounting systems
even replace the rear sight fi xture entirely, meaning that,
should the battery die, the user will have little choice but
to resort to point shooting. Just be aware that, due to the
A potential issue to be aware of: " Tactical " -size MRDs, like Bushnell's
RXS-250 (below, l.) may be too long to fi t within the slide cut of some
guns, while the " carry " -size Riton MPRD (below, r.) fi ts well.
