DISCLAIMER: I think I’ve been watching too many of these “Doomsday Prepper” shows on TV! I’ve been trying to diversify my home arsenal to prepare for various scenarios. Currently I own the following weapons: a) 5.56mm AR-15 b) 12Ga Rem 870 c) 45ACP RIA 1911 d) 9mm Glock 26 I like to have a diverse collection of weapons to assure that in a situation where ammunition and/or replacement parts becomes limited (i.e. natural disaster, loss of infrastructure, riots, etc.) I have a weapon or backup weapons that I can keep functional for as long as possible. Living in an urban environment my focus is Close Quarter Battle (CQB) arms. One of my primary concerns as it applies to diversification of weapons pertains to the availability of ammunition. As such, I try to stay focused on widely available calibers. I had planned to limit my pistols to 45ACP and 9mm calibers. I keep the 45ACP 1911 as MY primary handgun for self-defense. I purchased the 9mm Glock 26 primarily for my WIFE to use and become familiar with as the 1911 recoil is too much for her to handle. More recently, I’m finding myself interested in the 40S&W caliber. With more LE agencies adopting this caliber it is becoming as ubiquitous as 9mm and 45ACP with regards to availability. I am now in the market for a third handgun and am debating if I should diversify with a new 9mm pistol from a new manufacturer (i.e. the M&P9c) or a new caliber from a familiar manufacturer (i.e. the Glock 27) or a new caliber/manufacturer (i.e. the M&P40c). My thoughts on these three options are as follows. I've ranked the options in order of my current preference: (#1) 40S&W Glock 27: I really like the Glock 26 (I have the Gen4 version) and would love to get a G27 with the added punch of the 40S&W caliber. I’m nervous about needing to now stock a third pistol caliber ($$$), but like the idea of diversification. There is some interchangeability of the internal G26 and G27 parts as well as many of the accessories (holsters, etc.) which helps provide some redundancy should I need to cannibalize parts to get one of the two pistols back up and running in the event of a failure. One concern I have with the G27 is that it is nearly identical to the G26 and I’m concerned about my wife or I trying too slam a magazine of 9mm cartridges into the G27, or vice-versa, while trying to gain my composure after being startled awake in the middle of the night. There are ways to mitigate this (i.e. different colored mag floor plates, extensions, etc.) however, it still remains a concern. (#2) 9mm M&P9c: I’ve been eye-balling this gun for a while and almost bought one last week. I like the idea of supporting an American made product. I love the grips on this gun, but don’t care much for the trigger design/action. I like the idea of diversifying with a different manufacturer. Should there be a shortage of Glock parts due to some catastrophic event, I like that I would have a second brand to serve as a backup. I also suspect that my wife will prefer to shoot this gun due to the grip design compared to the G26. Also, the G26 tends to eject empty cases at her face approximately 10% of the time (yes….she’s probably limp-wristing) and I’m hoping the M&P9c won’t. As we don’t have access to renting or borrowing a M&P9c, I cannot verify this prior to purchasing. (#3) 40S&W M&P40c or M&P40 or M&P40 Pro Series: This purchase would be the ultimate in diversification. I tend to associate Glock with 9mm and Smith & Wesson with 40cal, so this might be the best solution yet. I would have a Glock chambered in the caliber they were originally designed for…. and a S&W Military & Police pistol chambered in a caliber now heavily being favored by “Police”. The only downside here is that I’m on the fence regarding the compact, full-size, or Pro Series. I like the M&P40c frame for concealment, while the Pro Series is ideal for target acquisition and recoil management. This brings about a whole different set of pros/cons I don’t even want to have to worry about right now. Is there anything else I’m overlooking? The best answer (to me)….is to buy them all! However, due to the fact that I value my marriage and my wife is getting tired of me buying new guns… this next purchase will be the last one for a while. As a result, I want to make the best possible purchasing decision so as to minimize regret. Any input you may have on my dilemma is GREATLY APPRECIATED!
