First time using GBB G17, and honestly, I'm quite blown away with how it performs. It has a solid kickback, and I have shot an actual G17, and the recoil isn't far off. In terms of cleaning, it's quite easy to clean it. My only recommendation is not to use silicone green gas; instead, try to find a silicone-free one that way you have less maintenance to clean your weapon system. Suppose you are looking to purchase your first pistol. In that case, this is highly recommended personally, the only downside is you cannot attach a sight; however, there are adapters, or you can change the whole slide but personally it looks a bit tacky. If any questions I will try to answer to the best of my ability
