Just an FYI--I took a risk and DID order from Ciener for my PT92. I received the 22lr conversion kit today, 3 weeks later. I had sent a personal check which is supposed to take longer.
I took it to the range right out of the box and it worked VERY well. I tried 4 different types of ammo and it consistently fired all of them, round nose, hollows, 36 and 40 grain high Vs. I did have 3 FTFs on feed issues. In hindsight, one of the mags was sticking (noticed that when I cleaned and lubed after). Even with that 3 out of 150 fired isn't bad.
I recently had an Advantage Arms kit for my Glock. AA worked fairly well on high end CCI but wasn't worth a damn on just about anything else. In this day and age of taking whatever you can find in 22lr, the Ciener kit wins hands down.
Just FYI Action Gun and Archery in Melbourne has some of these kits in stock also.
