@JPmbogo the question is more nuanced than “yours or theirs”.
I know that “yours” = not trash. High quality, reliable, well serviced rifles.
The problem comes in when we discuss “theirs”. Very few PHs client rifles meet the standards of an American safari hunter. Most PHs do not really know how to service weapons, or look after them. In many countries, you can count the amateur gunsmiths on one hand and the odds that any minor malady ever reached them before it became a major malady is more likely than not.
Certainly, there are exceptions to this rule, but you’d need to know a lot about them. My first PH assured me that his rifles were up to snuff and when I got there, I honestly would have pulled his license if I could have. Broken stock, ammo topped-off so many times the bullets spilled their powder in the action, zero bluing remaining on the whole gun, hadn’t cleaned it in a decade. His “client rifle” I sh&t you not was some 30-06 Remington of his grandfathers that preceded the model 700 and again, zero exaggeration, the trigger pull was about 15lbs. It also featured a low comb stock, 1.5” tall aluminum rings, a Tasco 4x fixed that had the seals blown, and the top of the rings had iron sights on them! Just an extreme example of how bad things can be.
As to you traveling with your own guns, it depends where you’re going and who you’re flying. I just went to TSA for a fresh 4457 earlier this week. I then applied directly myself with emirates for my rifle permission to fly permits, they were approved 4 hours later via email. (They used to say 30 days, now they say 3 days…but still, 4 hours is awesome) The only remaining rifle permit I need is Shall-Issue upon entry into Zimbabwe.
If you’re flying from USA via Emirates to Zim, i‘d say you’re crazy not to bring the guns you love and trust Since doing your own permits is so darned easy.
If you’re flying elsewhere using another carrier, it all depends.
