Its a matter of many things. Do you reload? You will spend some time trying different loads to see what works best in the gun. Its not as simple as taking any old major power load and sending it downrange. How much do u know or want to learn about that gun? There are many different options you can try to tune the gun to your preference. Trigger pull, recoil springs, trigger shape/length ect.. Then it will be mags and tuning. Learning how to properly shoot the new platform safely, since you are used to Glocks, its an entirely different feel/function. I have seen the consequences of someone learning a new gun with a super light trigger. Overall most good guns are pretty reliable. All that said, once you get it, you will never go back because its too much fun. For $5K, you can probably find a nice used gun here on the classifieds. I may be selling one soon myself, but thats for the classifieds..
