What can you tell me about my Luger?

OK, I took your advice and ordered the P08 recoil spring from Numrich. Clearly, there is a difference between the two springs. The upper spring is the original .30 Luger spring. The lower spring is the replacement spring that Numrich sent, ostensibly for firing 9mm. I just don't see how I'm going to compress that longer spring enough to engage the spring guide hook over the recoil lever. I had a hard enough time reinstalling the original shorter spring. Is there something wrong with this picture? Maybe this wasn't meant to be? I assumed the lower frames for P08's were identical between .30 Luger commercial models and 9mm models. Maybe this isn't the case?
