Which extension? (How many rounds does it add?)

I had a TacStar 10 round mag extension on my 1187. I was able to load 10 rounds into the mag. The mag tube, though, kept on walking out of its friction fit threaded collar. I replaced the TacStar with a Choate 10 round. Although it says '10 rounds' in the advertisement, it really isn't clear if it is 10 rounds in the mag or 9+1 (9 in the mag, 1 in the chamber). I was only able to load 9 rounds fully and only 2/3 or 1/2 of the 10th round. Here's, what I did to lengthen it a little bit to fit the 10th round.

The mag spring is held in place by a plastic plug at the front end of the mag. The plug was ~1/4". I replaced this with a washer of the proper diameter that would fit in the mag body but not throught tapered/crimped front end. The follower of the Chaote was also a bit thick. Instead of using this follower I just used the stock one that came with the gun. These two procedures were enough to barely allow me to seat the 10th round in the mag. To add slightly more space, I installed a Scattergun Tech sling mount that installs betwen the extended mag and the gun mag. Adds ~1/8". Now the 10th round fits without a prob.
