Need Some HK USP Help

[schmeky]

Just got my HK USP 45. Most impressive. However, it came with 2 safety/decock levers, and RH and a LH. I need to install the RH. How is this done? Do I get the LH one moving a little and then press the RH in behind it?

Any help would be appreciated

I got a USP 40 Version 1, RH; and wanted to trade it out for a lefty safety (version 2)...it was new, and i sent it to HK and paid S&H and for the part, but no work, IIRC. I take it yours is already used; but i'd give them a call first.
