When I first inserted the P229, it was extremely tight, and took a fair bit of force to get it to seat properly in the holster. A tight fit is generally a good thing in a new holster, and I assume this would loosen up some over time.
However, when I tried to draw the pistol, it kept getting seriously hung up in two places - the inboard part of the retention strap would hook on the decocker lever. The bottom edge of this strap is not flush with the interior surface of the holster, and is quite thick and stiff, so it will likely hang up on anything it comes in contact with. Hard to see in this pic, but it gives some idea:
At the very least, it seems like mounting this strap externally, rather than internal to the holster, would be a no-brainer. Unfortunately, the inboard part of the retention strap is riveted to the holster and not removable, or I would just ditch it entirely.
Also, when I would try to draw, the rear sight would get caught on the overlapping fabric seam on the inside of the holster lip, if I pushed the gun fully into the holster.
For these reasons, and the fact that they happened consistently, I pretty quickly determined that I would not carry my P229 in this holster. I then tried a M&P 4.25" and given the lack of external controls, particularly on the left side of the gun, it drew much more smoothly. I'm not sure how well this holster would work with other popular DA/SA options like Beretta, CZ, etc. or with a 1911, but my initial impression is that this holster was designed with streamlined, striker-fired pistols in mind.
The other issue I found was with the outboard half of the retention strap, which is elastic. I don't understand the need for elastic here, since the strap is already adjustable in terms of length, and it's not like it needs to fit super tight - it just needs to prevent the gun from accidentally dropping out of the holster. Unfortunately, with this elastic retention strap engaged, there is a fair bit of "give" that happens before the snap opens, which makes rapid deployment of the gun feel unacceptably sloppy, especially when seconds might count.
Here you can see how far my thumb is pushing over the retention strap to release it and it's still not opening:
Thankfully, the elastic part of the retention strap is entirely removable.
My suggestion here would be to ditch the elastic and just use an adjustable piece of non-stretch webbing. I would also suggest that the inboard part of the strap be entirely removable as well.
