For $60 you get a lot of fun and versatility for what you are spending. You could even take some of the Tactical accessories off like the sight rail and laser and sue them on some of your other air pistols with rails. No the Umarex TDP 45 TAC is not the most realistic or highest quality airgun out there but I bet you will get tired of shooting it before it wears out on you because it has such a simple internal firing mechanism. You can change the look by either taking some of the accessories off or adding even more, the choice is up to you!
