With that attitude you’re not going to get far on this forum. If you don’t want to make the effort to read what we already said, don’t expect someone to make that effort for you repeating again. Horrible impression for a novice.
You all buy from gunfire while smaller stores like redberet.pl which is also getting supplies from gunfire (and other wholesalers) sells stuff cheaper than gunfire on sales days.
Is this a good upgrade vs the stock one?

Cool to see the community is catching up on HPA carbine kits for pistols. Here’s my 1911 with an hpa hi cap mag I built 2-3 years ago, running on 120psi. A bit hot (2.1J) because of a long inner barrel (250mm) - not a cqb gun.
