Wonderful write-up! Thank you!
No, 9 mm and .45 buffer housings are different. 9 mm are still available, .45's are like hens teeth and tough to come by.
Here is a 9 mm one if you need it.
I know that there hasn't been a post on this thread for almost 3.5 years, but I just did a trade & end up with a HK P9S .45 TARGET, I'm buying parts for the gun. Would like to know if the P9S 45 used the same receiver as the 9mm. THANK YOU all for any information
I was able to buy two new HK P9S 45 mags for $109 each W O W !! that's expensive
I wonder how many rounds I can fired out of the P9S 45 before changing the buffer ???
