If you believe bigger is better, you are going to love where Glock innovative minds have been moving. At the 2015 SHOT Show Media Day at the Range, Glock debuted its new G40. Longer than any previous model, the G40 in the MOS (Mounting Optics System) configuration has a feature previously only available via a lot of custom gunsmithing.
Glock’s G40 Gen4 in MOS configuration starts with a full six inches of barrel length. This is going to increase the accuracy potential and give the competitive shooter, hunter or backyard plinker a huge advantage. The increased length also offers improved velocity and hit potential with a 15-round capacity magazine as well. Here is how Glock sums up the G40 Gen4 in MOS.
It is a powerful yet easily carried pistol for the outdoorsman, hunter and sport shooter. Designed to give the handgun hunter the ultimate choice in semi-automatic hunting handguns, the eight-inch sight radius improves shootability with open sights while the MOS system gives the shooter the ability to mount all popular reflex sights. Reflex sight advantages include faster target acquisition and enhanced long-range accuracy.
Now, I am about to commit sacrilege. At the first inkling of the MOS, I was more than a little thrilled. Being a fan of Glocks, I recently had a G22 customized to include a “melt.” This is a popular alteration to sink a reflex optic on the slide. The MOS accomplishes this just fine and will save you a few bucks at the gunsmith. The problem, and this could have just been on the model I tested, was that it did not go low enough to see through the iron sights.
Law Enforcement, particularly SWAT officers, often run a G22 with a melt. Department regulations—and common sense—dictate that any electronics can fail and if it is going to happen, eventually it will at a critical moment. As a result, most, if not all, departments require full visibility and use of iron sights as a back up to the reflex sight. While putting a single dot on the spot is indeed faster for target acquisition, you must have the irons available as a back up. This is true of a life and death situation, and would be just about as critical in my book while big-game hunting with a pistol.
The popularity of Glock and the requirements to keep shooters moving at the range means you do not get a lot of time to monopolize the guns of the representatives and this needs further investigation which will happen over the next couple of days at the display booth. However, for now, I am left a little flat if Glock’s new MOS design will allow an optic at the price of losing the irons as a back up. If that is the case, I’ll forgo the MOS and opt for a custom melt.
Currently, the MOS is available on the G34, G35, G40 and G41. Check back for an update soon.
