Recently bought a conversion kit for my 229 (non-railed). Once I got to looking at the magazines closely. I noted that there were some edges left over from the injection molding. Right at the top of the magazine in front of the feed lips. I shaved those down as they would sometimes catch the rim of the casings and cause a jam situation in which. You could not remove the magazine or easily clear the chamber. I have four magazines and with a few minutes of work they were all given the same de-burring. At the range I have so far put around 1000 rounds through the conversion. To include 200 CCI Mini Mag, 400 Remington Thunderbolt, 200 Federal Yellow Jacketh Bulk pack, and 200 Winchester Target bulk pack. While not flawless function. It is functioning at an acceptable level. I numbered the magazines. As it is my experience that you can sometimes narrow malfunctions down to a particular magazine. Haven't kept an exact count of the malfunctions. I would say less than a dozen in the 1000 or so rounds fired. I would also add that most of them came at the end of the sessions when the gun was fairly dirty. A couple FTF's where the slide did not go completely into battery. And a couple times it failed to strip a fresh round from the magazine. A quick cleaning after every 300 rounds would probably help considerably.
My ratings are as folllows: Scale of 1-10
Fit and finish= 9 Some of the machining on the barrell is a little "rough".
Accuracy =8 Don't have a ransom rest. But at 7yds. Supported, easily shoots less than 2 inch groups with cheap ammo.
Sights =6 Not a fan of 3 Dot. And it also ran out of elevation adjustment. It still shoots slighly high with a six o'clock hold.
Reliability=8 As stated ealier. Not flawless as when shooting .40SW. But acceptable.
Would I recommend this to my friends? Already have:) Going to the range today. Will keep a record of results.
