I got a real problem I have a lot of handguns but my favorite my Walther ppk . 380... the spring too stiff and increasingly difficult for me to pull the slide back to chamber the round,... So my question is can that spring be changed or altered without effecting the reliability.
The answers are Yes AND No, since it depends on the quality of the spring and who is doing the work for you.
I am not familiar with which neck of the woods you are located, but odds are that you can nevertheless find a good master smitty nearby who can competently fix your problem and/ or make any other other modifications to suit your particular needs.
Any ideas or suggestions for replacement?
As far as replacements go, Sidearms (other than family heirloom keepsakes) are important tools, which obviously are of no use to anyone if such cannot be competently and comfortably implemented by its user. You mentioned that you have a “lot of handguns”, but are you comfortable (and competently accurate) using all of same?
If not, consider trading those in for one/s which you are, so that you will always have a familiar and reliable back up/s, and it is important to choose the one or ones which you find that you are most comfortable in handling and accurate with when implementing.
Some dealers have ranges on site, (or nearby at least) and will let you try before you buy when it comes to selecting a perfect match / model which best suits you and meets your needs, and everyone purchasing / possessing any firearm should obviously not only be skilled in proper firearm safety, and should take professional courses offered whereby they can implement that firearm in simulated real life scenarios and various shooting positions, but as well take basic gunsmith courses so that they can field strip their weapon and fix most problems, long before any defecation hits the oscillation because in a real life or death situation/malfunction, 'Time Outs' don't apply. Ergo one's life is worth the investment to be 100% proficient. Having spare parts on hand is plain Commonsense 101
Edit: btw Spartacus Rex I love my mini 14. ...any suggestions for semi auto for feral dogs at a distance.
Mini 14's are a respectable and reliable rifle and oooh there's a Cromell Manufacturing (out of Kentucky) Select Fire conversion with a convenient folding stock available at 8.5K fiat, should one of your ponies find their way into the winner's circle
For semi-auto, Keltec has a nice bullpup in 7.62 NATO (.308 Win) at 1/5th the price:
I don't know if, or how often you visit any of the major Gun Shows, however there is no shortage of firearm manufacturers as well as the aftermarket guys who keep coming with amazing pieces / enhancements such as Muzzle Brakes / Recoil Compensators which permit the slightly petite slingers such as yourself to nevertheless pack the same wallop.
Notice that the above Keltec comes either in 18" Barrel or 24" "Hunter" and are threaded for Muzzle Brakes / Compensators, etc., and a competent master smitty can get you dialed in.
Personally I am so used to recoil that I would frankly miss it as it pretty much tends to give me a feeling of satisfaction sending a round down range knowing 'That's gonna hurt'.
Add that to the non local shale guys walking pipelines it can make a lone female feel awfully vulnerable out here in the sticks. this must sound ridiculous but I'm thinking I should be shouldering a rifle year round when I'm out in back acreage any thoughts?
Yes, the purpose of a Sidearm is to buy you time to fight your way back to where you left your Rifle, which you shouldn't have been without in the first place.
