I decided to not use my C-More Tactical Rail sight on my .460 Rowland 1911 when I had the twin revelations that the sight was probably not going to work with the mount I was using, AND C-More made a much smaller sight said to be designed to handle “high recoil” – the STS. I quickly ordered one of these sights, which was more expensive that my previous C-More sight, and the C-More mount which would place it on the slide – sometimes you just gotta “pay to play”!
The mount I am using is almost identical to the slide mount for the Burris FastFire, in that it has a flat metal piece tapped for two screws that slides into the dovetail slot where the original rear sight was mounted. A small change from the Burris mount is that a plastic “base” with an adhesive backing fits over the mounting plate to help position the metal sight base until the screws are in to hold it. This plastic piece is also curved to fit the top of the slide, and is specific to the type of pistol to be used. C-More suggests using the red, or “permanent” Loctite screw adhesive to hold the screws in place, and this should be a help with not loosening under recoil. If the mount ever needs to come off, it can be loosened with heat. The housing of this sight is aluminum, and seems very sturdy.The C-More has good adjustments for elevation and windage that are “locked” with a separate screw after zeroing, to keep the dot from wandering. As with most sights of this type, the “on/off” switch is not especially easy to get to, but since battery life on these is extremely long, it is probably best to just turn it on at the beginning of a hunt or range session and leave it on until packing up to go home.The switch has positions for “off”, “automatic”, and full on. I have found it pretty much impossible to adjust it to a lower intensity than in the “AT” position, which is about halfway, but the automatic adjustment seems to work for most conditions. Bringing the dot on target is so much faster than getting on target with open sights that there is really no comparison. A plastic cover comes with the mount, which will be good for deflecting dirt and avoiding smudges.
I have not as yet had a chance to test fire the .460 Rowland with this sight set-up, to make sure it actually stays mounted securely, and that the sight can take the punishment of a “slide ride” from the powerful Rowland cartridge, but I have high hopes that it will be fine on both counts. This sight is much lighter than my previous C-More unit, and the pistol is heavy enough with the Clark Custom comped barrel that I really don’t need additional weight. Being mounted low to the bore will make it easier to zero with less adjustment, and should help accuracy as well.
As always, I will be updating this post with results from the shooting sessions. Right now, I have a conflict between wanting to get it ready to shoot some hogs, and not wanting to scare what few deer might be wandering near my small property into the Corpus area by repeatedly firing the big Rowland.
Although a holographic, or “reflex”, type sight has no magnification, it is much “faster” to acquire the target than with even a very low power pistol scope. The unlimited eye relief means it can be mounted any distance from the shooter, and he/she can shoot with both eyes open. A scope’s biggest advantage over open sights is that it eliminates having to line up the rear sight, front sight, and target for each shot – just put the crosshair on the target and fire when ready! Once the pistol is zeroed, the reflex type of sight is even better, because the red dot can be any place in the viewing screen and still be on target – it does not have to be centered.
