Are pistol optics similar to the rule of thumb for hunting optics? $$ scope = $$ rifle? I can sort of understand hunting optics….a good scope could make the difference between tagging out or not.
When it comes to pistol optics for use only at the range…is there a general rule of thumb on how much to spend….like 1/2 the $$ spent on the pistol?
So if say I spent $240 on the M&P…get a used vortex venom for about $100.
The price of optics are based on quality (clarity, brightness, accuracy, ability to retain zero, ruggedness, features) and competition.
Would you put a $100 optic on a Ruger .22LR target pistol? Sure since the forces created by the pistol are pretty light.
Would you put that $100 optic on a 9mm Sig P320? Not sure it's designed or manufactured for the recoil that pistol creates.
Would you use it for competitions on your Glock .45ACP? I doubt it.
The price of the pistol was what you paid to meet your needs. If it's just a range toy, you probably paid toward the low end. If it's for CCW and HD, you probably pick something above that. You need to pick your optic the same way regardless of what you paid for the pistol.
Would you put a $1000 optic on a Ruger 10/22 .22LR rifle? That would be overkill for the range, recoil and application a .22LR needs. Same for the pistol.
Pistol optics are holographic, just like an AR red dot. That alone means it's not going to be inexpensive. But, the size of the dot, the color of the dot, the brightness, and the clarity are what most people compare when shopping for one. After that, it needs to be compatible with the firearm you choose. Rugged enough to handle the slide movements at the force generated by the caliber ammo.
I consider optics similar to how I see computer monitors. You might need to upgrade your computer, but the monitor is usually the one thing you keep between 1,2,3 or more PCs. That's why I get the size, image quality, features and brand name I can afford so I know I'll be happy with it for many years no matter what it's connected to.
So, look at it as a long term purchase. Get what you know you will want to keep for many years. Otherwise you'll be shopping for a replacement as soon as you find a reason to no longer like it.
